NEET BIOLOGY

Detailed explanation-1: -Enzymes are highly specific for the substrate. So they cannot be used for different types of reactions. As lock and key model assumes that a high degree of similarity between the shape of substrate and the geometry of the binding site of the enzyme.

Detailed explanation-2: -In an enzyme activity, the substrate must bind with the enzyme to become a catalyst of a chemical reaction. And most enzymes are highly specific particularly to the nature of the substrate they bind to.

Detailed explanation-3: -Enzymes are biological catalysts which speed up biochemical reactions. According to the most widely accepted theory, enzymes bind to the substrate molecule and form a transition state. During the progress of a reaction the substrates are separated from products by an energy barrier which the substrates need to cross.

Detailed explanation-4: -Answer and Explanation: Of the following regarding enzymes, enzymes being consumed by the reaction they catalyze is incorrect. Enzymes are special in that they’re able to catalyze many different reactions without being consumed or used up by the specific reaction.

Detailed explanation-5: -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.
