Study Notes
Citric Acid Cycle Overview
- Acetyl CoA is the key molecule entering the citric acid cycle, serving as the starting point for energy production.
- ATP is generated through the phosphorylation of ADP during the cycle, highlighting its role in energy transfer.
- The main products of the citric acid cycle include ATP, FADH2, NADH + H+, and CO2.
Relationship with Glycolysis
- Each glucose molecule processed in glycolysis yields 2 acetyl CoA that enter the citric acid cycle, linking the two metabolic pathways.
- The citric acid cycle produces 6 NADH + H+ for each glucose molecule, emphasizing its significance in electron transport and energy production.
