Let re-learn some stuff and earn some points back. These are questions missed by most of you on the exam. You can only earn up to a maximum of 120 points total (your exam 1 score + what you earned here). One point per correctly answered question (20 points) 1. Oxidative phosphorylation requires all of the items listed below except a. ATP synthase in the correct position in the membrane. b. The flow of electrons from NADH to protein in the membrane. c. A matrix more positively charged

is the permanent increase in size and the dry mass of the organism. Plants keep on growing for their whole lives. Animals stop growing at a certain age. Excretion Excretion is the process of the removal of the metabolic waste from the body. Metabolism is the term given to the entire chemical reactions taking place in the body. Plants store this waste in their leaves so that it is removed when they fall off. Sensitivity Sensitivity is the response of a change in the environment of the organism

Answer: active transport to move glucose up its concentration gradient. Question 4 1 out of 1 points The 1985 Nobel Prize in Physiology or Medicine was awarded to Michael Brown and Joseph Goldstein for their work on cholesterol metabolism. Brown and Goldstein investigated the cause of remarkably high levels of circulating cholesterol found in certain families. Just as remarkable was the high incidence of heart disease in these families. What Brown and Goldstein found was not what

function‚ energy sources and energy expenditure all have great influence on the success of weight loss. For efficient metabolic function the human body requires an ongoing energy source. This energy source comes from the food that has been consumed. Metabolism refers to chemical reactions responsible for energy transfer within the body (Moffet‚ Moffet‚ & Schauf‚ 1993). Once food enters the body it must go through a series of chemical events in order to be converted to chemical energy ready to be utilised

control plant metabolic processes such as respiration (Evert RF‚ Eichhorn SE & Perry JB 2013). This experiment focuses on the enzyme catalase. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of cell metabolism that can be toxic to the cell (Evert RF‚ Eichhorn SE & Perry JB 2013). The

MCB 3020 Exam TWO Study guide 1. List the laws of thermodynamic and describe their relevance in the chemical reactions 2. Define the standard reduction potential. Why aerobic grow generates the highest amount of energy (ATP). How this value plays a role in organization of electron transport system. Compare Eo of aerobic and anaerobic respiration 3. Describe the flow of electron in fermentation and respiration. What happened to the electron in each of the above processes 4

Excretion Questions Chaiken of Biology 1. Distinguish between excretion and egestion/defecation. Why is excretion necessary for life? EXCRETION INCLUDES BALANCING (HOMEOSTASIS) REACTION PRODUCTS‚ TOXINS‚ MOLECULES IN EXCESS AND TOO LITTLE. EGESTION INCLUDES MOLECULES THAT ARE EXITING YOUR ANUS CHEMICALLY UNCHANGED 2. Name three excretory organs of humans. What liquids carry the urea that is excreted? Which organ of another studied organism resembles the nephron in function? THREE

half protein & half carb per snack...Ie: Cashew Butter & Celery‚ Houmous & Cucumber‚ Ham & Melon or Fruit & natural nuts & seeds are just a few suggestions xxx 3. Eat every 2-3 hours to keep your energy levels from falling & to maintain your metabolism. This will cause u to burn body fat more effectively. 4. Drink a min of 2lit H20: Not drinking enough water can cause you to feel fatigued due to dehydration. Avoid sugary sodas‚ juice‚ squash or sweetened beverages that can cause energy

enzymes; they contain a catalytic (active) domain and a regulatory domain‚ which must be either removed or altered to expose the active site. * Apoptotic enzymes – Caspases; exhibit similar regulation as zymogens. * Chapter 3: Cellular Metabolism * Pyranose – ring structure that glucose and many other 6-carbon sugars are capable of forming; it is in either an alpha or beta configuration. * Breakdown of ATP to ADP or of ADP to AMP releases approximately 7 kcal/mol of energy. *

Enzymes are protein‚ they are used to catalyse metabolisms in all organisms. They break down complex molecules and build up complex molecules from simple molecules‚ these two processes are catabolic reaction and anabolic reaction respectively. Enzymes are needed in these two processes to catalyse releasing and taking up ATP molecules. Different sequence of amino acid produces different structure of protein‚ which determines the property of protein‚ thus each kind of enzymes has its unique active
