Metabolic pathways

Metabolism is defined as the group of life-supporting, enzyme-mediated chemical reactions in organisms. A metabolic pathway is a set of these chemical reactions that involve anabolism (synthesis of complex biomolecules) and catabolism (breakdown of biomolecules into small molecules) that occur inside a cell. Metabolites are the reacting substances, products, and intermediate substances of an enzymatic process that are altered by a series of chemical events catalyzed by enzymes.

Expert Solution

Step 1

When oxygen is available, aerobic respiration will takes place. In eukaryotic cells, the process of glycolysis occurs during which pyruvate molecules produced at the end of process are transported into the mitochondria. Mitochondria is the sites of cellular respiration. There, pyruvate molecule is transformed into an acetyl group which is picked up and get activated by acompound called coenzyme A (CoA). The final compound formed is called acetyl CoA.
