Question

26. Based on our discussion in class, high levels of NADH would likely A. cause pellagra B. stimulate glycolysis C. slow down the movement of molecules through the citric acid cycle D. slow down oxidative phosphorylation E. break down carbohydrates 27. What purpose does fermentation serve? A. It regenerates NAD* from NADH to keep glycolysis going in the absence of oxygen. B. It allows for the production of NADH, which keeps the electron transport chain going. C. It produces an abundance of ATP when oxygen is present. D. Under aerobic conditions, it drives the formation of acetyl CoA, which then feeds into the citric acid cycle E. It produces reactive alcohols in muscle cells to reduce levels of acid 28. Coenzyme A is important because A. it oxidizes pyruvate B. it oxidizes oxaloacetate C. it reduces CO2 D. it produces NAD+ E. It transfers an acetyl group to oxaloacetate 29. Malate + NAD+ > oxaloacetate + NADH gets oxidized and gets reduced In the above reaction, A. Malate, NAD+ B. oxaloacetate; NADH C. oxaloacetate; NAD+ D. NADH; malate E. NAD+; malate

Answer 1

e to pyruvate mostly . The high level or NADH inhibits ginconeogenesis by preventing the oxida of lactate to pynurate This high conc. a NADH may cause reverse reaction to become dominata predomi as a result lactate will be accum As gluconeogenesis will be inhibited Citric acid cycle also be inhibited On slowed down.. - But this high lever or MADH would not coluse pellagra, and it inhibits glycolysis It does not slow down oxidative phosphonylation and it does not break down carbohydrates.
