Study Notes
TCA Cycle and HMP Shunt - Study Notes
- TCA Cycle Location: The Tricarboxylic Acid (TCA) cycle occurs in the mitochondria.
- Pyruvate to Acetyl CoA Enzyme: The enzyme Pyruvate Dehydrogenase Complex (PDH) converts Pyruvate to Acetyl CoA.
- Thiamine Deficiency & PDH Complex: Wernicke's Encephalopathy is a condition caused by thiamine deficiency which affects the PDH complex.
- ATP Production in TCA Cycle: One turn of the TCA cycle directly produces one ATP molecule.
- Citrate Synthase Inhibitor: ATP inhibits the enzyme Citrate Synthase.
- HMP Pathway Molecule Exclusion: ATP is not produced in the HMP pathway.
- HMP Regulatory Enzyme: Glucose-6-Phosphate Dehydrogenase (G6PD) is the primary regulatory enzyme of the HMP shunt.
- High HMP Activity Tissue: Liver tissue has high HMP activity due to fatty acid synthesis.
- NADPH Role in Erythrocytes: NADPH in erythrocytes reduces glutathione.
- Oxidant Drug in G6PD Deficiency: Primaquine is an oxidant drug which can cause hemolysis in G6PD deficiency.
