1. Explain why citric acid (Krebs) cycle is a series of redox reactions. How many "turns"
of the citric acid cycle would be required to completely oxidize one glucose molecule?

Expert Solution
Step 1

It is a sequence of redox reactions taking place in the cells as a part of metabolism. It is the process of oxidation of acetic acid (acetyl-CoA is oxidized to form carbon dioxide with the help of coenzymes). It also produces ATP. 

The cycle takes place in the mitochondria of the cell. It is also Kreb's cycle, tricarboxylic acid cycle.

It uses oxygen and produces CO2 and other waste products.
