Choose all of the following true statements. Hint: 6 statements are true. □ If an electron moves from an atom of higher electronegativity to an atom with lower electronegativity, energy is released. O Glycolysis occurs with or without oxygen present. Other biomolecules such as lipids, disaccharides, and proteins can enter the biochemical pathway of aerobic respiration just not directly into the first step of glycolysis. Molecules other than glucose can be broken down and used to build up ATP in aerobic respiration. Glycolysis occurs during both alcohol and lactic acid fermentation, producing 2 net ATP. The higher the electronegativity of an atom, the tighter it holds an electron and the lower its potential energy. Water is the final electron acceptor of the ETC in aerobic respiration. Each protein component of the ETC in aerobic respiration is more electronegative than the last.

ATP production would increase since glycolysis would be using less ATP. The Krebs cycle production of FADH2 would increase. O The Krebs cycle would continue to function at a normal rate. O The Krebs cycle production of NADH would decrease.

A) The role of oxygen in oxidative phosphorylation (cellular breathing) is: -To be the last electron acceptor in the electron transfer chain -To hydrolyse carbohydrates - To add hydrogen ions to pyruvic acid at the end of glycolysis -To provide electrons for NADP reduction -To provide hydrogen ions B) Which molecule has the most potential energy? -glucose -phosphate -fructose 1-6 diphosphate -ethanol -I'ATP C) What is the product of fermentation in yeasts? -carbonic acid -oxygen -ATP -lactic acid -ethanol
The image below shows part of a key catabolic pathway. If an individual had a deficiency for the enzyme required at point "X", would they still be able to produce a high rate of ATP during very strenuous exercise? ATP in Glucose Prep. phase Payoff phase ļ - MacRoc Pyruvate →→→ Anaerobic fate of pyruvate ATP out ▬OD OF 1- HP 01 -- Select one: O a. No, because NAD* will not be regenerated by lactate dehydrogenase. The reduction of NAD+ to NADH is a required step during the payoff phase of glycolysis. O b. No, because lactate dehydrogenase is required for the continued recycling of NAD+ to NADH, thus allowing glycolysis to continue. Oc. Yes, because pyruvate dehydrogenase is necessary to produce acetyl-CoA, which under these conditions will feed into the citric acid cycle. Od. Yes, because this enzyme is responsible for the substrate-level phosphorylation necessary to maintain the ATP input for the preparatory phase of glycolysis.

1a. If you wanted you could take a glucose molecule and convert it to pyruvate via glycolysis and convert it back to glucose via gluconeogenesis. What is the cost of doing so in ATP equivalents? Show how you determine the cost via reactions (no structures). Explain in bioenergetic terms how the conversion of pyruvate to phosphoenolpyruvate in gluconeogenesis overcomes the large, negative standard free- energy change of the pyruvate kinase reaction in glycolysis. b. C. The consumption of alcohol (ethanol), especially after periods of strenuous activity or after not eating for several hours, results in a deficiency of glucose in the blood, a condition known as hypoglycemia. The first step in the metabolism of ethanol by the liver is oxidation to acetaldehyde, catalyzed by liver alcohol dehydrogenase: CH3CH2OH + NAD+ -> CH3CHO + NADH + H+ Explain how this reaction inhibits the transformation of lactate to pyruvate. Why does this lead to hypoglycemia?
When muscles contract, a chain of events result in greater activity by the TCA cycle. All of the following are links in that chain EXCEPT: The ADP concentration increases. Rate of respiration and oxygen consumption increases. The electron transport chain produces more water. The concentration of NADH decreases and the concentration of NAD+ increases. 2) (True or False )______The concentration of oxaloacetate drops and TCA cycle is halted which leads to the synthesis of ketone bodies. 3) NADPH is used for: a) Oxidizing vitamin E b) Oxidizing glutathione c) Reductive biosynthesis of fatty acids d) β-oxidation of fatty acids
