Question

Which is true about the relative production of ATP and NADH from carbohydrates in glycolysis and citric acid cycle (=Krebs Cycle)?

A. Citric acid cycle produces much more ATP per glucose than glycolysis does
B. Glycolysis produces much more ATP per glucose than citric acid cycle does
C. Citric acid cycle produces much more reduced NADH per glucose than glycolysis does
D. Glycolysis produces much more reduced NADH per glucose than citric acid cycle does

Answer 1

C. Citric acid cycle produces much more reduced NADH per glucose than glycolysis does

Step-by-step explanation:

* The citric acid cycle is a better way to make energy than glycolysis because it makes more NADH, which is used to make energy.

* **Citric acid cycle:** A process that breaks down glucose into carbon dioxide and water, and produces ATP and NADH.

* **Glycolysis:** A process that breaks down glucose into pyruvate, and produces ATP and NADH.

* **NADH:** A molecule that carries electrons and is used to produce ATP.

* **ATP:** The energy currency of the cell.
