In a laboratory investigation, a student is studying the role of pepsin in animal digestion. Pepsin helps break down proteins into simple molecules.
The student adds pepsin to a test tube containing egg whites. The test tube mixture changes from opaque (cloudy) to clear after eight minutes.
Which statement most likely describes the functions of the pepsin and egg whites during the investigation?

Pepsin is a product that reacts with the egg white enzyme, and the egg whites break down into nucleic acid products.

Pepsin is a reactant in the chemical reaction with the egg white substrate, and the egg whites break down into fatty acids.

Pepsin is the substrate that takes part in the chemical reaction with the egg white enzyme, and the egg whites break down into sugar products.

Pepsin is an enzyme that acts on the egg white substrate, and the egg whites break down into amino acid products.
