The Standard Free energy of S and P C. The relative concentrations of S and P D. a and b E. b and c - Answer -E. b and c Consider the free energy diagram below, which describes the energy states of molecules undergoing the reaction X <-> Y. Raising the temperature of the reaction would reduce the size of which arrow? A. a B. b C. c D. d E. none of the arrows would decrease, they would only increase with increased temperature. - Answer -B. b If "R" accumulates, which enzyme(s) would "R" most likely "feedback inhibit" A. "c", B. "f", C. "m", D. A and C (watch out for capital vs lower case here!), how about c and m? E. B and C how about f and m? I'll use numbers in my exam! - Answer -E. B and C how about f and m? I'll use numbers in my exam! Respiration results in the formation of more ATPs are generated per glucose than does fermentation because... Need assistance on Online classes, Exams & Assignments?

Electrons can be stripped from NADH via the electron transport chain in respiration C. Pyruvate is oxidized during fermentation D. a and b E. b and c - Answer -D. a and b ATP is used as an "energy currency of the cell" because: A. The diphosphate bond is unusually stable, for a covalent bond B. Hydrolysis of the diphosphate bond has a high positive ∆G C. Hydrolysis of the diphosphate bond has a high negative ∆G D. ATP is a building block of DNA E. Both a and d - Answer -C. Hydrolysis of the diphosphate bond has a high negative ∆G NADH can be used for biosynthetic reactions, or it can be "cashed in" for ATP. NAD+ is reduced to NADH in every one of these steps except... A. Glycolysis B. Pyruvate oxidation C. The citric acid cycle D. Respiratory electron transport. - Answer -D. Respiratory electron transport. Anaerobic respiration yields fewer ATPs per NADH than aerobic respiration because... A. Respiration can't occur in the absence of O2. B. Fermentation is naturally inefficient C. O2 is a very powerful oxidizing agent D. O2 is a very powerful reducing agent E. O2 has always been plentiful in the Earth's atmosphere - Answer -C. O2 is a very powerful oxidizing agent The terminal electron acceptor in the noncyclic photosynthetic electron transport chain is... A. Oxygen B. Water C.
