What's the end product of Kreb cycle?

Answer 1

The end products of the Krebs cycle (also known as the citric acid cycle or TCA cycle) include:

1. Carbon Dioxide (CO2): Two molecules of CO2 are released for each acetyl-CoA that enters the cycle.
2. NADH: Three molecules of NADH are produced per acetyl-CoA.
3. FADH2: One molecule of FADH2 is generated.
4. GTP (or ATP): One molecule of GTP (or ATP, depending on the cell type) is produced.

These reduced coenzymes (NADH and FADH2) are then used in the electron transport chain to produce ATP, which is the primary energy currency of the cell. The cycle also plays a key role in the catabolism of carbohydrates, fats, and proteins.
