Detailed explanation-1: -Which of the following best describes the action of an enzyme? Explanation: Enzymes are biological molecules that help catalyze reactions by lowering the energy of activation and increasing the rate of a reaction.

Detailed explanation-2: -Lock-and-key model is a model for enzyme-substrate interaction suggesting that the enzyme and the substrate possess specific complementary geometric shapes that fit exactly into one another. Enzymes are highly specific. They must bind to a specific substrate before they can catalyze a chemical reaction.
