Distinguish between Glycolysis and TCA cycle.

The process of glycolysis takes place in the cytoplasm. A molecule of glucose is oxidized step by step in this process and two molecules of each i.e. Pyruvic acid, ATP, NADH₂ and water is formed. Molecules of pyruvic acid formed in this process are converted into molecules of Acetyl-Coenzyme-A. Two molecules of NADH₂ and two molecules of CO₂ are released during this process. Meanwhile, in TCA, both molecules of acetyl-CoA enter the mitochondria. A Cyclic chain of reactions known as a tricarboxylic acid cycle is operated on it in the mitochondria. Acetyl part of acetyl-CoA is completely oxidized during this cyclical process and molecules CO₂, H₂O, NADH₂, FADH₂ are derived.
