Citric acid cycle irreversible steps
WebOxidation is the breakdown of a molecule as it loses at least one of its electrons.This phase is made up of 2 irreversible steps: Step 1: Glucose-6-phosphate is oxidized to form lactone. ... Pyruvate will then become acetyl CoA, which can go into the citric acid cycle. In the … WebSteps in the Citric Acid Cycle. Step 1. The first step is a condensation step, combining the two-carbon acetyl group (from acetyl CoA) with a four-carbon oxaloacetate molecule to form a six-carbon molecule of citrate. CoA is bound to a sulfhydryl group (-SH) and diffuses away to eventually combine with another acetyl group.
