Similarity between Glycolysis and Krebs cycle
Both glycolysis and Krebs cycle are steps of respiration in which energy is released in the form of ATP and NADH. The process of glycolysis and the Krebs cycle both occur inside the cell of the living organism.
Difference Between Glycolysis and Krebs Cycle
The main difference between Glycolysis and Krebs Cycle is that: Glycolysis is the first step of respiration in which one molecule of glucose undergoes partial oxidation to produce two molecules of pyruvic acids, ATP, NADH, and water. It is an anaerobic process that occurs in the cytoplasm of the cell. Krebs cycle is the second step of respiration in which the pyruvic acid produced in glycolysis degrades after complete oxidation to produce carbon dioxide and water. It is an aerobic process that occurs in the mitochondria of the cell. Glycolysis is the linear sequence that does not require oxygen whereas the Krebs cycle is a cyclic sequence that requires oxygen.
