Question

Enzymes are proteins that help increase the rate of chemical reactions inside cells. These proteins are composed of many similar molecules called amino acids. Which of the following suggests that the shape of an enzyme determines the enzyme's function?

Enzymes are specific to a substrate.

Enzymes can operate in a wide range of conditions.

Enzymes are activated by neighboring molecules.

Enzymes are found in all life-forms.

Answer 1

The statement that best suggests that the shape of an enzyme determines the enzyme's function is:

Enzymes are specific to a substrate.

This specificity indicates that an enzyme's active site has a particular shape that matches the shape of its specific substrate(s), which is crucial for the enzyme's ability to catalyze a reaction. If the enzyme's shape is not compatible with the substrate, the enzyme cannot function properly.
