Homework Answers
1) CORRECT ANSWER: It is produced in glycolysis and consumed in the Citric acid cycle
EXPLANATION: After glycolysis, pyruvate is converted into acetyl CoA in order to enter the citric acid cycle.
2) CORRECT ANSWER: Electron transport
EXPLANATION:
- Oxidative phosphorylation, which involves the electron transport chain that produces maximum ATP.
Add Answer to:
Under aerobic conditions, when is pyruvate produced and consumed? O It is produced in the citric...

We have discussed fermentation as a mechanism for regeneration of NAD for glycolysis under conditions when an ETC is not available for NAD regeneration. Embden-Meyerhof glycolysis converts one NAD to NADH for each molecule of pyruvate produced. Fermentation of pyruvate to propionic acid converts one NADH to NAD for each molecule of pyruvate fermented. Which of the following statements is TRUE of metabolism under conditions that force the use of pyruvate fermentation to propionate? It should be possible to perform...

Should have been inhibited fermentation citric acid cycle oxidation of pyruvate electron transport glycolysis cristae males no ATP Which statement about fermentation is false? Fermantation is used as a way of making a small number of ATP's per glucose molecule when the mitochondria are not working. Fermentation is used as a way of making a small number of ATP's per glucose molecule when the oxygen is temporarily not present. Heat is a product of fermentation. The main of fermentation...
