NURSING ANM AND GNM

Detailed explanation-1: -Answer and Explanation: The given statement is true. Enzymes: It is a biological substance; generally used to enhance the reaction (like metabolism). It is similar to the catalyst used in a chemical reaction.

Detailed explanation-2: -An enzyme therefore catalyzes a specific chemical reaction but may be able to do so on several similar compounds.

Detailed explanation-3: -Summary. Specificity is attained when a chemical reactant (the substrate) interacts weakly with an enzyme’s active site to form a bond. The production and dissolution of covalent bonds is the only sort of chemical reaction that an enzyme can catalyse.

Detailed explanation-4: -This statement about enzymes is true: Enzymes accelerate reactions by lowering the activation energy. Enzymes are proteins whose three-dimensional form is key to their function.

Detailed explanation-5: -The correct option is (a) They are highly specific in the reactions they catalyze. Enzymes are highly specific because they contain a three-dimensional substrate binding site that binds to the corresponding three-dimensional substrate molecule.
