A single ___________ produces two molecules of acetyl CoA, which enters the citric acid cycle.

The correct answer is: Glucose molecule

• A single glucose molecule that enters the citric acid cycle produces two molecules of Acetyl Co-A
• Additionally, reduced high-energy molecules like NADH and FADH2 are created.
• Since each glucose molecule produces two acetyl-CoA molecules, the Krebs cycle must be completed twice to produce the four CO2, six NADH, two FADH2, and two ATPs.
