Question

1. what is the significance of the citric acid cycle in cellular respiration? a. it generates nadh and fadh2 for the electron transport chain. b. it occurs outside the mitochondrion. c. it directly produces water and oxygen. d. it breaks down glucose into pyruvate.

Explanation:

The Citric Acid Cycle, also known as the Krebs cycle, occurs in the mitochondrial matrix. It generates NADH and FADH2 which carry high - energy electrons to the Electron Transport Chain for ATP production. Glycolysis breaks down glucose into pyruvate outside the mitochondrion. Water and oxygen are not directly produced by the Citric Acid Cycle.

Answer:

a. It generates NADH and FADH2 for the Electron Transport Chain.
