How Alcohol Affects The Human Body
To understanding the metabolism of alcohol, we should know that what is alcohol, how is it affect human body. Alcohol is being considered one of the most commonly used drugs because it has adverse impacts on human’s health through how it’s metabolized.

Alcohol is a compound of hydrogen, carbon and oxygen, which can be combined in many different ways. The commonest as known as ethyl ethanol, which is a specific alcohol compound (C2H5OH) and formed from the fermentation of yeast, sugars and starches. This alcoholic formation also releases carbon dioxide (Simon, Reece, Dickey 2010, p.103). The compounds of alcohols are structurally similar to carbohydrates, consist one or more hydroxyl (OH) group. Ethanol is the

This process occurs primarily in the liver. Through oxidation, the acetic acid then is converted to acetic acid radical which is a poison and relatives to formaldehyde. This acetic acid radical combines with enzymes in the liver and enters the Krebs Cycle which is the second stage of cellular respiration, also referred to as citric acid cycle that is fueled by acetyl CoA formed after glycolysis in cellular respiration. Chemical reactions in the cycle complete the metabolic breakdown of glucose molecules to carbon dioxide and water (Simon, 2010, p.G-5). The cycle occurs in the matrix of mitochondria and supplies most of the NADH molecules that carry energy to the electron transport chains (Simon, 2010, …show more content…
When teens and young adults chronically consume excessive amounts of alcohol, they may permanently damage brain structure and function. (Thompson, Manore, 2008) Their intellectual function and memory may lose. In addition, early exposure to alcohol increases risk of future alcohol addiction and may contribute to lifelong deficits in memory, motor skills, and muscle coordination (NIAAA., Alcohol Alert, No. 68, April 2006.) Older males’ bodies have lower possibility to produce alcohol dehydrogenase. If drink same amount of alcohol, older males are more intoxicated than younger men. Menopausal women hormone changes obviously, which lead women to tend to more intoxicated than younger women at same amount of alcohol. People with liver damage also tend to more intoxicated because of their liver do not work as good as normal livers, they tend to produce less alcohol dehydrogenase. However, the frequent heavy drinkers tend to less intoxicated on larger amount of alcohol because their livers used to produce more alcohol dehydrogenase to break down the acetic

    he Krebs Cycle also expressed as: CH3C(=O)C(=O)O− (pyruvate) + HSCoA + NAD+ → CH3C(=O)SCoA (acetyl-CoA) + NADH + CO2 is the main pathway in all aerobic organisms. Basically it’s the way that cells produce energy for itself, but the only issue is it requires the presence of oxygen. In total eight reactions that take place in the mitochondria, and these reactions result in two carbon molecules and oxidizes it into carbon dioxide. Step 1 Citrate synthase bridges to Oxaloacetate substrates which can then bind to Acetyl–CoA’s acetyl group, which drops off the A Co-enzyme. This in turn created citrates for usage later in the Krebs cycle. This six-carbon molecule will be degraded, and biotransformed back into Oxaloacetate.Step 2The citrate isn't…

    The citric acid cycle begins after the first stage of glycolysis is completed. The two carbon molecules are converted into acetyl CoA compound. Two ATPs are produced per each molecule of glucose by the citric acid cycle. When these compounds are reduced, they are transported by electron carriers to the next stage. The citric acid cycle occurs only when oxygen is present in the mitochondrion after the cell splits during the first phase glycolysis.…

    Aerobic cellular respiration is a pivotal process in which organisms carry out in order to sustain life. It is characterized by the release of energy from organic compounds by means of chemical oxidation within the mitochondria of the cell. The reactants are glucose and oxygen, and after a series of complex steps, the products of carbon dioxide, water, and ATP + heat are released. Thus, cellular respiration is an exergonic process, since heat energy is released in order to do cellular work. The overall process can be encapsulated by the following equation: C6H12O6 + CO2 6CO2+ 6H2O+ 586 kilocalories of energy/mole of glucose oxidized. This reaction seems very straightforward, however there are numerous enzyme-mediated reactions that occur within it that are not so perceptible from the simplified equation. Cellular respiration consists of three major stages: The first is Glycolysis; (occurring in the cytosol) in which chemical energy is harvested by oxidizing glucose into two 3 carbon molecules of pyruvate, and thus producing a net of 2 ATP molecules through substrate-level phosphorylation, as well as a net of 2 NADH molecules. Subsequently, the Krebs Cycle commences after 2 pyruvate molecules are converted to 2 Acetyl CoA molecules in the intermembrane space of the mitochondria. During the Krebs Cycle (occurring in the mitochondrial matrix)4 CO2 molecules are released, 1 ATP molecule is formed (for each turn of the cycle), and the reduced forms of 6 NADH and 2 FADH carry the electrons to the next step: the Electron Transport Chain. This occurs in the inner membrane of the mitochondria, and consists of many electron carriers that pass electrons (donated by NADH and FADH2) along through a series of redox reactions. At the end of the chain, oxygen acts as a final electron acceptor and it reduced them to form water. A proton motive force, or H+ gradient,…

    The Citric Acid Cycle is a series of enzyme-catalysed reactions that take place in the mitochondrial matrix of all aerobic organisms. It involves the oxidation of the acetyl group of acetyl CoA to two molecules of carbon dioxide. Each cycle produces one molecule of ATP by substrate-level phosphorylation, and reduces three molecules of NAD and one molecule of FAD for use in Oxidative Phosphorylation. The cycle is preceded by Glycolysis, which also occurs in anaerobic respiration, and the pyruvate dehydrogenase complex, which occur in the cytoplasm and the mitochondrial matrix respectively. In aerobic respiration, glycolysis breaks down one molecule of glucose and two molecules of pyruvate, and gives a net product…

    This cycle also called the “Krebs cycle”, completes the breakdown of glucose all the way to CO2, one of the waste products off cellular respiration. The enzymes for the citric acid cycle are dissolved in the fluid within mitochondria. Glycolysis and the citric acid cycle generate a small amount of ATP directly. They generate much more ATP indirectly, via redox reactions that transfer electrons from fuel molecules to NAD+, forming NADH.…

    The Citric acid cycle also known as the Krebs cycle, to honor the scientist who first studied it, is a cyclical metabolic pathway located in the matrix of the mitochondria. At the start of the citric acid cycle, the C2 acetyl group carried by CoA joins with a C4 molecule, and a C6 citrate molecule results. The CoA returns to the preparatory reaction to be used again. During the citric acid cycle, the acetyl group is oxidized, and the rest of the CO2 we breathe out per glucose molecule is released, both NAD+ and FAD accept hydrogen atoms, resulting in NADH and FADH2, and the substrate-level ATP synthesis occurs, as ATP results.…

    Cellular respiration is an ATP-producing catabolic process in which the electron receiver is an inorganic molecule. It is the release of energy from organic compounds by chemical oxidation in the mitochondria within each cell. Carbohydrates, proteins, and fats can all be metabolized, but cellular respiration usually involves glucose: C6H12O6 + 6O2 → 6CO2 + 6H2O + 686 Kcal of energy/mole of glucose oxidized. Cellular respiration involves glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is a catabolic pathway that occurs in the cytosol and partially oxidizes glucose into two pyruvate (3-C). The Krebs cycle occurs in the mitochondria and breaks down a pyruvate (Acetyl-CoA) into carbon dioxide. These two cycles both produce a small amount of ATP by substrate-level phosphorylation and NADH by transferring electrons from substrate to NAD+. The Krebs cycle also produces FADH2 by transferring electrons to FAD. The electron transport chain is located at the inner membrane of the mitochondria and accepts energized electrons from enzymes that are collected during glycolysis and the Krebs cycle, and…

    With regards to alcohol has many long term effects. The bloodstream transports blood all over the body. As soon as alcohol is consumed, it goes into the bloodstream and spreads throughout the body. It can affect the bones; it was said in, “Effects of Heavy Drinking,” that alcohol can make arthritis more painful by inflaming the joints that are affected. Another example of liquor affecting the bones is gout which is another form of arthritis that harms the foot. The consumption of alcohol makes this disease more worse and more painful. Drinking too much can be followed up by an increase in blood pressure and diabetes which can then lead to different heart conditions (“Effects of Heavy Drinking.”). Another thing that can be harmed by alcohol…

    Substance use disorders are complicated illnesses that present unique threats to women 's health. Medical research is showing that women who abuse alcohol, tobacco and other drugs may develop addictions and substance-related health problems faster than men. Alcohol consumption is most common among women between the ages of 26 and 34 and women who are divorced or separated. The National Institute on Alcohol Abuse and Alcoholism defines a light drinker as one who drinks about 1 to 13 drinks a month; a moderate drinker as one who drinks about 4 to 14 drinks a week; and a heavier drinker as one who has more than two drinks a day. Women are more vulnerable to alcohol-related organ damage, trauma and interpersonal difficulties such as liver and brain damage, heart disease, breast cancer, violence, and traffic crashes. With liver damage Women develop alcohol-induced liver disease in a shorter time period than men even if they consume less alcohol. And, women are more likely to develop alcohol hepatitis and die from cirrhosis (liver disease). Brain damage shows studies of the brain, as seen via magnetic resonance imaging (MRIs), showing that women may be more vulnerable to brain damage due to alcohol consumption than men. Heart diseases are among heavy drinkers, women develop heart disease at the same rate as men, despite the fact that women consume 60 percent less alcohol than men over their lifetimes. Some studies have shown a link between moderate or heavy alcohol consumption and an increased risk for breast cancer. College women who drink are more likely to be the victims of sexual abuse. And high school girls who use alcohol are more likely to be the victims of dating violence. With traffic crashes even though women are less likely than men to drive after drinking, women have a higher relative risk of dying in a car accident if they 're driving even at similar blood alcohol concentrations to men.
