Question

How does the shape of an enzyme affect its function?

A. The shape holds molecules that provide more energy to the reaction.

B. The shape is matched to the reactants, holding them in place and lowering the activation energy.

C. The shape helps the enzyme synthesize extra reactants for the reaction.

D. The shape helps lower the ΔH of the reaction.

Answer 1

Answer:

The shape of the enzyme determines which chemical reaction it will speed up. ... -May strain the bonds of the substrate or put chemical groups of the active site in the correct position to speed up the reaction.

Explanation:

Answer 2

Answer:

The correct option is (B) The shape is matched to the reactants, holding them in place and lowering the activation energy.

Explanation:

• Enzymes can be defined as biological catalysts for biochemical reactions.
• They speed up the reaction by lowering the activation energy.
• There are several types of enzymes. Each type works on a specific substrate. Example- Protease breakdown proteins only.
• According to the Lock and Key theory, the enzyme is the lock and the substrate is the key. The enzyme will only bind with that substrate that can fit into it.
• An enzyme has an active site where the substrate of a specific shape bind.
