Pepsin is an enzyme that digests _______

Explanation

Pepsin is an enzyme that helps to digest a certain type of nutrient. The question is asking which nutrient this is. The options are starch, sugar, lipid, fat, and protein. To answer this question, we need to know what pepsin does and what nutrients it is responsible for breaking down. Pepsin is an enzyme that is produced in the stomach and helps to break down proteins into smaller molecules called peptides. Peptides are then further broken down into amino acids, which can be absorbed by the body and used to build new proteins. Therefore, the correct option is E: protein. It is important to note that other enzymes are responsible for breaking down other nutrients, such as amylase for starch, lipase for lipids, and sucrase for sugar. Each nutrient requires a specific enzyme to break it down properly. In summary, pepsin is an enzyme that helps to digest proteins into smaller molecules called peptides. Therefore, the correct option is D: protein. To learn more about enzymes and nutrient digestion, please read the relevant sections of the recommended textbooks
