Which of the following statements is true of enzymes

A. they change shape after a reaction

B. They don’t provide an active site for substrates to bind in a reaction

C. They’re unusable after a reaction

D. They act on a specific type of substrate in a reaction

Option D

They act on a specific type of substrate in a reaction is true of enzymes

Explanation:

The enzyme‘s existing position adheres to the substrate. Enzymes increase chemical reactions by inducing substrates collectively in an optimal familiarization, thus constituting a supreme chemical condition for the reaction to transpire.

A reactant in a chemical reaction has denominated a substrate when operated superimposed by an enzyme. There may be one or further substrates for all kinds of enzymes, based on the appropriate chemical reaction. In remarkable reactions, a single-reactant substrate is split down into various products. In others, pair substrates may evolve unitedly to design one more abundant molecule.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

i'm pretty sure its b i might be wrong though!
