Answer to Question #23345 in Biochemistry for Rabiya

Question

name some of the vivo biochemical reaction(other than digestion) catalyzed by enzymes.

Answer 1

Enzymes catalyse the numerous methabolic reactions of hydrocarbonates, lipids and proteins and nucleic acids in vivo. For instance, peptidyl transferase reaction: the amino (NH2) group of the aminoacyl-tRNA, which contains the new amino acid, attacks the ester linkage of peptidyl-tRNA (contained within the P site), which contains the last amino acid of the growing chain, forming a new peptide bond. This reaction is catalyzed by peptidyl transferase. Glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis in animals by releasing glucose-1-phosphate from the terminal alpha-1,4-glycosidic bond. Phospholipase is an enzyme that hydrolyzes phospholipids into fatty acids and other lipophilic substances.
