Enzymes are able to create gaps in cell walls that allow reactants to enter cells.
Enzymes are able to create gaps in cell walls that allow reactants to enter cells.

Enzymes are able to create gaps in cell walls that allow products to leave cells.

Answer 1

The correct response is:

Enzymes have a shape that specifically fits the reactants, like a key in a lock.

This description illustrates the specificity of enzymes in catalyzing reactions, where the enzyme's active site is tailored to bind only to particular substrates (reactants), similar to how a specific key fits into a unique lock.
