Question

Summarize what happens during the Krebs cycle.

A. Glucose is converted into pyruvic acid.
B. High-energy electrons are released.
C. Carbon dioxide is produced in energy-extracting reactions.
D. Oxygen is generated as a final product

Answer 1

The Krebs cycle, also known as the citric acid cycle, is the second stage of cellular respiration. It converts pyruvate into high-energy molecules and produces carbon dioxide. It also releases high-energy electrons.

Step-by-step explanation:

The Krebs cycle, also known as the citric acid cycle or the tricarboxylic acid cycle, is the second stage of cellular respiration.

It involves the conversion of pyruvate, which is generated by glycolysis, into high-energy molecules such as NADH, FADH2, and ATP. During the cycle, a two-carbon acetyl-CoA molecule is systematically processed, resulting in the production of carbon dioxide as a waste product and the release of high-energy electrons that are captured in NADH.
