Final answer:
A peptidase is the enzyme specific for hydrolyzing peptide bonds, which are the covalent bonds linking amino acids within proteins or peptides.
Step-by-step explanation:
Proteins and peptides are composed of amino acids linked together by a special type of covalent bond called a peptide bond. This bond forms through a dehydration synthesis reaction, where the carboxyl group of one amino acid combines with the amino group of another, releasing a molecule of water. To break this bond, specific enzymes are required.
The correct enzyme that would be specific for breaking a peptide bond is a peptidase. Peptidases are enzymes that hydrolyze peptide bonds within proteins or peptides. The other enzymes listed, such as amylase, cellulase, and lipase, target different types of bonds. Amylase breaks down glycosidic linkages in carbohydrates, cellulase hydrolyzes the bond between glucose molecules in cellulose, and lipase cleaves the ester bonds in fats or lipids.
Therefore, the enzyme that would be specific for a peptide bond is c. peptidase.
