Question

different between glycolysis and TCA cycle

Answer 1

The main difference between glycolysis and Krebs cycle is: Glycolysis is the first step involved in the process of respiration and occurs in the cytoplasm of the cell. While Krebs Cycle is the second process of respiration which occurs in the mitochondria of the cell. Both are the process involved in respiration with the aim of fulfilling the energy requirement of the body.

So Glycolysis is defined as the chain of the reactions, for the conversion of glucose (or glycogen) into pyruvate lactate and thus producing ATP. On the other hand, Kreb cycle or citric acid cycle involves the oxidation of acetyl CoA into CO2 and H2O.

Respiration is the important process of all the living being, where oxygen is utilised and carbon dioxide is released from the body. During this process, energy is released, which is used to perform various functions of the body. Apart from the above two mechanisms, there are various other mechanisms of respiration like Electron transport system, pentose phosphate pathway, anaerobic breakdown of pyruvic acid, and terminal oxidation.

In the provided content we will discuss the general difference between two most important mechanisms of respiration which are glycolysis and Krebs cycle.
