Question

arrange the steps of the citric acid cycle in order, following the oxidation of pyruvate to form acetyl-coa.

Answer 1

The steps of the citric acid cycle after the oxidation of pyruvate to form acetyl-CoA are condensation with oxaloacetate to form citrate, conversion of citrate to isocitrate, and oxidation of isocitrate to form α-ketoglutarate.

Step-by-step explanation:

The steps of the citric acid cycle after the oxidation of pyruvate to form acetyl-CoA are as follows:

1. Step 1: Acetyl-CoA condenses with oxaloacetate to form citrate, a six-carbon molecule.
2. Step 2: Citrate is converted to isocitrate.
3. Step 3: Isocitrate undergoes oxidation to form α-ketoglutarate, producing NADH and CO₂.

These are the first three steps of the cycle, and they set the stage for the subsequent reactions that continue to harvest energy from the acetyl-CoA.
