Question

Explain why for each molecule of glucose that enters glycolysis there is more than one turn of the Krebs cycle?

Answer 1

The Krebs cycle turns twice for each molecule of glucose that enters glycolysis.

Step-by-step explanation:

The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that occur in the mitochondrion of eukaryotic cells. It is an important part of cellular respiration and is responsible for the production of ATP, NADH, and FADH2. When glucose enters glycolysis, it is converted into two molecules of pyruvate. Each pyruvate then goes through oxidative decarboxylation to produce two molecules of acetyl-CoA. Each acetyl-CoA then enters the Krebs cycle, resulting in two turns of the cycle for each molecule of glucose.
