Citric Acid Cycle

Steps of Pyruvate Dehydrogenase

First step of the citric acid cycle

oxaloacetate + acetyl-CoA → citrate

Steps of Pyruvate Dehydrogenase

First step of the citric acid cycle

oxaloacetate + acetyl-CoA → citrate

Second step of the citric acid cycle

citrate → isocitrate

Third step of the citric acid cycle

isocitrate → alpha-ketoglutamine

fourth step of the citric acid cycle

alpha-ketoglutamine → succinyl-CoA

fifth step of the citric acid cycle

Succinyl-CoA → Succinate

sixth step of citric acid cycle

succinate → fumarate

seventh step of citric acid cycle

fumarate → malate

eighth step of citric acid cycle

malate → oxaloacetate

full citric acid cycle

Which steps are irreversible

oxaloacetate + acetyl-CoA → citrate

isocitrate → alpha-ketoglutamine

alpha-ketoglutamine → succinate CoA

What steps regulate the citric acid cycle

the 3 irreversible steps

Citric acid cycle regulation diagram

what can any citric acid cycle intermediate be a precursor of

gluconeogenic precursors because all can be converted to oxaloacetate through the cycle
