Question

One turn of the CAC only produces one ATP (or GTP). Explain how most of the energy of the four oxidation steps in the CAC is conserved?

Please help explain and where could I find more information on this

Answer 1

The Krebs cycle, also called the citric acid cycle or the tricarboxylic acid cycle, is a sequence of chemical reactions that convert glucose, protein and fat into energy to living cells in the form of adenosine triphosphate or ATP. Living cells use the energy of ATP for protein synthesis from amino acids and replicating deoxyribonucleic acid or DNA.

In this cycle the total oxidation of the two carbon atoms of the acetyl radical, which are removed as CO2 is achieved; High energy electrons in successive oxidations obtained are used to form NADH and FADH2, which then enter the respiratory chain.

• Reaction 1: citrate synthase (citrate oxaloacetate)

Reaction 1 Krebs Cycle: citrate synthase. The active site of the enzyme, acetyl-CoA active to make a carbonaceous related to center of oxaloacetate. Following binding between the two molecules, the thioester group (CoA) is hydrolyzed, thereby forming the citrate molecule. The reaction is highly exergonic (?G '
