(a)
To determine: The reason of decrease in the yield of citric acid when the [Fe3+] varies from the optimal value.
Introduction:
Citrate is the first product of citric acid cycle. it is obtained from the enzymatic activity of citrate synthase on oxaloacetate and acetyl CoA. Citrate is produced commercially and added as flavoring agent in some foods, juices, and soft drinks.
