Some enzymes remove single amino acids from proteins by beginning at the amine or N-terminus. True Enzymes can selectively cleave specific peptide linkages between specific amino acids within a protein, thereby creating larger peptide fragments. False Enzymes hydrolyze only double bonds. False

true-Enzymes can selectively cleave specific peptide linkages between specific amino acids, within a protein, thereby creating smaller peptide fragments.

true-Some enzymes remove single amino acids from proteins by beginning at the amine or N-terminus.

false-Enzymes hydrolyze only double bonds.

Explanation: enzymes are protein in nature. they  help to speed up the rate of biological reaction

enzymes as a biological catalyst, breaks large molecule of nutrient into smaller molecules.  they are found in the body naturally, they help in chemical reaction and the digestive system of the body. they are of three types which are amylase, lipase and protease  of which has specific function in the human body.
