Utilization of TCA Intermediates
Many of the substrates in the TCA cycle can be used in other areas of the cell for other reactions as well.
- Oxaloacetate (OAA) can go through gluconeogenesis and make glucose again, or it can form aspartate and join the amino acid crowd.
- Citrate can be converted to a fatty acid.
- Alpha-ketoglutarate can be modified into glutamate and joint the amino acid crowd like OAA.
- Succinyl CoA can become a slew of different things including heme groups or chlorophyll in a plant cell.
