What is the primary purpose of the Krebs Cycle?

The primary purpose is to generate high-energy electron carriers like NADH and FADH2 for the Electron Transport Chain.

Which molecule enters the Krebs Cycle to begin the process?

Acetyl-CoA is the molecule that enters the Krebs Cycle.

What is produced from one acetyl-CoA molecule after one cycle of the Krebs Cycle?

One cycle produces 3 NADH, 1 FADH2, 1 GTP (or ATP), and 2 CO2 molecules.

What happens to the carbon atoms of acetyl-CoA in the Krebs Cycle?

The carbon atoms are released as carbon dioxide (CO2).
