Step TCA (Kreb Cycle) Metabolism

Vocabulary flashcards covering the enzymes and ATP yield of each step in the TCA/Kreb cycle based on the lecture notes.

Pyruvate dehydrogenase

The enzyme that converts Pyruvate to acetyl CoA, producing $3\,ATP$.

Citrate synthase

The enzyme that facilitates the reaction of Acetyl CoA + oxaloacetate to produce Citrate.

Aconitase

The enzyme that converts Citrate into iso citrate.

iso citrate dehydrogenase

The enzyme that converts iso citrate to x.keto glutarate, yielding $3\,ATP$.

Ketoglutarate dehydrogenase

The enzyme that catalyzes the transition from x.keto glutarate to succinyl CoA, yielding $3\,ATP$.

succinate CoA synthetase

The enzyme that converts succinyl CoA into succinate, yielding $1\,ATP$.

succinate dehydrogenase

The enzyme that converts succinate into Fumarat, yielding $2\,ATP$.

Fumarase

The enzyme that converts Fumarat into malate.

malate dehydrogenase

The enzyme that converts malate into oxaloacetate.
