The enzyme that speeds up the breakdown of proteins in food is D. Pepsin.

Amylase is an enzyme produced by the salivary gland and pancreas that breaks down carbohydrates or starch by adding water molecule or hydrolysis. Glucose on the other hand is a simple sugar or in chemical form C6H12O6 and it is not an enzyme. Saliva is the fluid secreted by the salivary gland and it is mostly water. Saliva contains amylase that helps to break down carbohydrates. Pepsin is an enzyme that is found in the stomach and it breaks protein into peptides.
