Study Notes
Citric Acid Cycle
- The primary function of the citric acid cycle is to generate energy for the cell by producing ATP, NADH, and FADH2 from the breakdown of acetyl-CoA.
- The citric acid cycle occurs predominantly in the mitochondria, where it plays a crucial role in cellular respiration.
- The final electron acceptor in the citric acid cycle is oxygen, which is used to generate ATP during oxidative phosphorylation.
- The major source of acetyl-CoA for the citric acid cycle is the breakdown of carbohydrates, fats, and proteins, which are converted into acetyl-CoA through glycolysis, beta-oxidation, and other catabolic pathways.
- Approximately 2-3 ATP are synthesized in the citric acid cycle, which accounts for a significant percentage of the total ATP produced during cellular respiration.

Description
Test your knowledge of the Citric Acid Cycle, also known as the Krebs Cycle or Tricarboxylic Acid Cycle, which is a crucial metabolic pathway for energy production in the body. This quiz will challenge your understanding of the cycle's role in ATP synthesis, the oxidation of Acetyl CoA, and its utilization of oxygen.
