In the second step of glycolysis, two hydrogen atoms are removed from a molecule of glucose-3-phosphoglycerate(G3P) and transferred to a molecule of NAD. What is the name of this step?
Correct answer: C. Payoff phase
- A. Preparatory phase
- B. Lactic acid fermentation
- C. Payoff phase
- D. Carbon fixation
Explanation
A. This is the first step of glycolysis.B. In absence of oxygen, pyruvic acid is converted into lactic acid. This happens after glycolysis, when pyruvic acid is formed.D. Refers to the initial incorporation of carbon dioxide into organic molecule Rubp in Calvin cycle.
