Pepsin is a digestive enzyme that pepsin is a digestive enzyme that splits maltose into monosaccharides. is manufactured by the pancreas. stabilize fat-water emulsions. is denatured and rendered inactive in solutions with low ph. begins the hydrolysis of proteins in the stomach.

The correct option is: begins the hydrolysis of proteins in the stomach

Explanation:

Pepsin is a protease enzyme that is synthesized by the stomach. It is the main gastric enzyme that helps in the digestion of proteins molecules present in the food.

The pepsin enzyme catalyzes the acid hydrolysis of the peptide bond in the proteins at a very low acidic pH of 1.5-2.0.

This enzyme becomes inactive at pH 6.0 and gets fully denatured or irreversibly inactivated as the pH increases to 8.0.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
