Study Notes
Regulation of TCA Cycle
- The activities of the dehydrogenases of the TCA cycle are determined by the NAD+/NADH and FAD/FADH2 ratios.
- The rate of the TCA cycle is crucially determined by the availability of NAD+ and CoA-SH.
- The regulatory process that couples the activity of the respiratory chain to the generation of ATP is called respiratory control.
- The rate of ATP synthesis is strongly dependent on the proton gradient across the inner mitochondrial membrane.
- The availability of NAD+ and CoA-SH is an effective determinant of the TCA cycle activity.
- The crucial factor in determining the rate of the TCA cycle is the availability of NAD+ and CoA-SH.
- The TCA cycle activity is very dependent on the ATP/ADP ratio, which affects the activity of isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase.
