Study Notes
Krebs Cycle Overview
- The Krebs cycle is the second of four processes necessary to extract energy from glucose.
Location and Process
- The Krebs cycle takes place within the mitochondrial matrix.
- Pyruvate is formed in the cytosol and imported into the mitochondria.
- Pyruvate is converted to acetyl-CoA and then imported into the mitochondrial matrix.
- Acetyl-CoA enters the citric acid cycle.
Function and Regulation
Amphibolic Function
- The TCA cycle has both anabolic and catabolic functions.
Anabolic Functions
- α-ketoglutarate is used for the synthesis of some non-essential amino acids.
- Succinyl CoA is used in heme synthesis.
Regulation of TCA Cycle
- There are three regulatory enzymes in the TCA cycle.
- One of the regulatory enzymes is citrate synthase.
