Study Notes
Cellular Respiration
- In eukaryotes, the citric acid cycle occurs in the mitochondrial matrix.
- The vast majority of ATP during catabolism is generated in the oxidative phosphorylation stage.
- Oxidative phosphorylation takes place in the mitochondrial inner membrane in eukaryotes.
- The remaining carbon atoms from carbohydrates, amino acids, and fatty acids are released in the citric acid cycle stage.
- The main function of the TCA (Tricarboxylic Acid) cycle, also known as the citric acid cycle, is to generate energy for the cell by producing ATP, NADH, and FADH2 during cellular metabolism.
