Study Notes
Citric Acid Cycle
- Also known as the Krebs cycle or tricarboxylic acid (TCA) cycle
Acetyl-CoA
- Primary source: breakdown of carbohydrates, fats, and proteins
Reducing Agents
- Citric acid cycle produces NADH and FADH2 as reducing agents
Acetate in Citric Acid Cycle
- Fate: converted to acetyl-CoA, which enters the citric acid cycle
NADH Utilization
- Generated NADH is utilized by the electron transport chain in the mitochondria to generate ATP
