Which is the Main Organic Molecule That is Digested by the Secretions

Question

Which is the main organic molecule that is digested by the secretions of the stomach?
A) carbohydrate
B) lipid
C) nucleic acid
D) protein

Accepted Answer

The main organic molecule that is digested by the secretions of the stomach is protein. This is because the stomach releases digestive enzymes such as pepsin and hydrochloric acid that break down protein into smaller molecules called peptides. Carbohydrates and lipids are primarily digested in the small intestine, while nucleic acids are digested in both the small intestine and stomach.
