1. The overall equation for Cellular Respiration is 6O2 + C6H12O6 6H2O + 6CO2 + energy. Overall, it is the reverse reaction of photosynthesis, but chemically, the steps involved are very different. All you have to do is just flip both sides of the equation of photosynthesis, and you have the opposite, which is the equation for cellular respiration. They are reversible chemical reactions, meaning that the products of one process are the exact reactants for the opposite process. The end result of Cellular Respiration is 38 ATPs that can then be used for cellular work. 2. The four major steps in Cellular Respiration are: Glycolysis, Transition Reaction, the
Krebs cycle (or citric acid cycle), and the Electron

The Transition Reaction occurs in the mitochondria. The Krebs cycle occurs in the mitochondrial matrix, the liquid-y part of the mitochondria. The Electron Transport Chain occurs in the christae of the mitochondria, the folded membrane inside the chloroplast. Glycolysis produces 2 ATP for every glucose. The Transition Reaction produces a molecule called Acetyl CoA. The Krebs cycle results in the production of only 4 ATP, but produces a lot of NADH.
The Electron Transport Chain produces 32 ATP for every glucose. 3. The Lo-carb Atkins and South Beach diets are based on occasions when the body runs out of carbohydrate reserves to use as fuel. Draining the carbohydrate levels and reserves of your body, so that to make daily energy (ATP), your body has to turn to an alternate source of fuel, which are fats and proteins. (FATS) Triacylglycerol reserves (located in unpleasantly strategic locations on your body ...) tend to be stored in adipose cells. Lipases are released into the bloodstream and break down fats in the bloodstream (from the fats and oils we eat) or travel to adipose cells. Lipases break the glycerol head away from the fatty acids in our

    Biochemistry GRT1   Lipids are molecules that are not soluble in water but can be dissolved in non-polar substances such as alcohol or chloroform (Mandal, n.d.). Lipid molecules are stored in adipose, or fat tissue, and can be broken down in our bodies to form an energy called ATP. To do so, the lipid molecule is dissected into its base pieces, glycerol and fatty acids. Each of the fatty acids is then broken down into two-carbon pieces and acetyl CoA is formed from each carbon piece.…

    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,…

    Lipids in the form of triaglycerols are a major source of energy storage. Initially, the lipids are absorbed in the small intestine through emulsification into small droplets by bile salts; thus forming mixed micelles. During low blood sugar levels, the secretion of glucagon and adrenalin hormones activates the release of the enzyme triacylglycerol lipase, which subsequently stimulates the release of fatty acids in adipocytes. The blood protein serum albumin then transports the fatty acid through the bloodstream to tissue such as the renal cortex, heart and skeletal muscle in order to provide energy through β-oxidation.…

    The Great Metabolic Race

    At the beginning of the race, the athlete’s body is metabolising fats. Fats is the preferred energy source of some tissues including that of the heart, liver and resting skeletal muscle, as glycogen storage is conserved for times of emergencies or fast paced activities, where energy needs to be rapidly supplied. Fats are also known as lipids and are stored in the athlete’s adipose tissue. This particular storage form is more reduced than carbohydrates, and therefore, can store more energy per unit weight. The lipids used for energy storage within the athlete’s body are in the form of triaclyglycerols. The low glucose level in the blood of the athlete is the factor that contributes to the mobilization of the stored triacylglycerols, which causes the release of hormones, glucagon and adrenalin, to stimulate the release of fatty acids in adipocyte tissues by activating the enzyme traicyclglycerol lipase. This enzyme breaks down the triacylglycerols into fatty acids and glycerol, while the serum albumin transports the fatty acids through the bloodstream to deliver them to the target tissue, and ultimately into the muscle cells where the fatty acids can be oxidised. The process of the oxidation of fatty acids, β-oxidation will be discussed in depth at the 45-minute mark of the…

    Photosynthesis is the process by which plants create food for themselves which occurs in the cytoplast organ of the cell. They absorb carbon dioxide, water, and solar energy to produce glucose and oxygen (Doc C). Cellular respiration on the other hand, is the process occurring in the mitochondria by which organisms create energy to power cellular processes. This process takes in glucose and oxygen to create carbon dioxide, water, and energy in the form of ATP (Doc C). These processes follow the law of conservation of matter and energy as the amount of products is always equal to the amount of reactants in a chemical equation. So the amount of glucose and oxygen created during photosynthesis is equal to the amount of carbon dioxide and water used and the amount of carbon dioxide and water produced during cellular respiration is equal to the amount of glucose and oxygen used. Many people notice that the products of cellular respiration are the reactants of photosynthesis and the products of photosynthesis are the reactants of cellular respiration. This is because the two processes work together to provide organisms with food and…

    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…

    This creates a slightly basic environment, meaning the semiliquid becomes alkaline. This is when the intestinal digestion begins. The pancreas secrets pancreatic fluid into the intestine. This fluid contains, Amylase, Trypsin, and Lipase. Amylase is released first in the fluid. Amylase breaks down starches into their component sugars. Trypsin hydrolyzes polypeptides, converting them into amino acids. Lipase breaks down fats into glycerol and fatty acids. The bile acids produced by the liver act as natural detergents to dissolve fat in water and allow the enzymes to break the large fat molecules into smaller molecules, some of which are fatty acids and cholesterol. Bile acids combine with the fatty acids and cholesterol and help these molecules to move into the cells of the mucosa. In these cells the small molecules are formed back into large molecules, most of which pass into lymphatic vessels in the intestine called lacteal. These small vessels carry the fat to the veins of the chest, and the blood carries the fat to storage depots in different parts of the…
