Citric acid cycle/Krebs cycle-3 steps

Citric acid cycle/

Krebs cycle-3 steps

Step 1 Prep work

pyruvic acid is oxidized generating 2 NADH. Then it is decarboxylated, removing 2Co2’s , leaving 2 carbon compounds called acetyl. The Acetyl compound is attached to an enzyme producing Acetyl- CoA.

Step 2 entering the cycle

CoA of acetyl-CoA attaches Acetyl to 4 carbon compounds, thus reforming citric acid.

step 3 turning of the cycle-

Citric acid is oxidized and decarboxylated twice to produce 4 NADH and 4 Co2. CoA is attached to the remaining 4 carbon compounds.CoA is removed from the 4 carbon compounds releasing energy. Energy released phosphorylates to form 2 ATP. 4 carbon is generated 2 FADH2. And are oxidized again to generate 2 NADH
