Detailed explanation-1: -As well as being highly potent catalysts, enzymes also possess remarkable specificity in that they generally catalyse the conversion of only one type (or at most a range of similar types) of substrate molecule into product molecules.

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: -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-4: -The correct answer: The statement that is false about the enzymes d. A specific enzyme can catalyze a variety of chemical reactions. The enzymes are basically proteins that are produced from the secretory cells.

Detailed explanation-5: -Enzymes are substrate selective and reaction specific. The structure of the enzyme made it selective towards its substrate as every enzyme has a different structure. According to the demand of the reaction, every reaction is specific to a particular type of enzyme. No other enzyme can act on that reaction.
