citric acid cycle

Step 1 to enter TCA cycle

glucose is converted to pyruvate via glycolysis
Step 2 to enter TCA cycle

pyruvate is converted to acetyl co-A via pyruvate dehydrogenase

NAD+ is reduced to NADH
Step 1 of citric acid cycle

Acetyl co-A is converted to citrate via citrate synthase
Step 2 of TCA
citrate --> isocitrate
- enzyme: aconitase
- internal redox, carbon rearrangement
Step 3 of TCA
isocitrate -> alpha ketoglutarate
- enzyme: isocitrate dehydrogenase
- redox: NAD+ -> NADH
- CO₂ is produced
Step 4 TCA
alpha-ketoglutarate --> succincyl co-A
- enzyme: alpha-ketoglutarate dehydrogenase
- redox: NAD + --> NADH
- CO₂ is produced
Step 5 TCA
succinyl co-A --> succinate
- enzyme: succinyl co-A synthetase
- redox: GDP --> GTP
- **high
