1);B
Oxidize NADH to NAD+.
Lactic acid and al alcoholic fermentation generate NAD+
so,that glycolysis can continue to produce ATP.
In lactic acid fermentation pyruvate from glycolysis change to lactic acid.
In alcoholic fermentation , pyruvate change into alcohol and carbon dioxide.

QUESTION 25 The citric acid cycle cannot function if o2 is not available; why is this OA. O2 is required for the redox reactions of the citric acid cycle. B. All of these answers are correct OC. The electron transport chain will not function without 02, thus the NAD+ and FAD needed for the citric acid cycle will not be regenerated. OD. None of these answers are correct O E 02 is the final electron acceptor of the citric acid...

What is the function of cytochrome c in the electron
transport chain?
Question 3 of 4 To answer this question, you may reference the Metabolic Map. What is the function of cytochrome c in the electron transport chain? o It reduces two molecules of Q to QH2. It oxidizes NADH to NAD+. It oxidizes FADH2 to FAD. It transports two electrons from NADH or FADH to complex III. It transports an electron from complex III to complex IV.

1. Select the TRUE statement about the citric acid cycle. A. Isocitrate dehydrogenase is a multienzyme complex that is very similar to the pyruvate dehydrogenase complex B. The two decarboxylation steps occur right after each other, first via oxidative alpha- decarboxylation, then via oxidative beta- decarboxylation. C. In one turn of the cycle, the two carbons that enter the cycle as acetyl CoA are the same two carbons that are released as CO2. D. A flavin containing dehydrogenase enzymes oxidizes...
