Question

Describe the reaction of the citric acid cycle and for each step explain the type of reaction, enzyme involved, substrate and product, if the reaction is reversible or irreversible, any coenzyme or prosthetic group involved, and location.

Answer 1

Reaction of citric acid cycle

(Shown in the image).

Citric acid cycle is also known as tricarboxylic acid cycle or krebs cycle. This process is the oxidation of acetyl- Co A into ATP and CO2. The reactant for the cycle is acetate which comes from the acetyl Co A and water which reduces NAD+ to NADH. So NADH is generated by citric acid cycle through oxidative phosphorylation.

Location of the all reactions in the citric acid cycle takes place in the matrix of mitochondria.

Now we will see the cycle through steps.

All the above things like substrate, product , type of reaction, Enzyme involved , reaction (reversible or irreversible) and coenzyme or prosthetic group is shown in table form in the image.
