Question

Enzyme trypsin converts:
(A) Amino acid into protein.
(B) Glucose into glycogen.
(C) Starch into sugar.
(D) Proteins into amino acids.

Answer 1

Hint :We know that the enzymes are catalysts. They are proteinaceous in nature. They can be of various types. One category of enzymes includes proteolytic enzymes which help in the breakdown of proteins into amino acids. Trypsin enzymes are formed from the trypsinogen by the action of enterokinase in the small intestine.

Complete Step By Step Answer:
Enzymes are the biocatalyst which helps in the catalyzation of biochemical reactions. They themselves do not take part in the reaction, instead they help the reaction to proceed in a particular reaction. There are various types of enzymes such as proteases and proteolytic enzymes. These enzymes help in the breakdown of proteins to their respective amino acids. There is hydrolysis of peptide bonds during the process of proteolysis. These enzymes are present in all types of organisms and are involved in the catabolism and breakdown of proteins and cell signaling.
In this question, we have asked about trypsin enzymes. Trypsin is an enzyme that helps us digest protein. We can also call it a proteolytic enzyme or proteinase. As we already mentioned Pancreas secretes an inactive proenzyme called trypsinogen. The trypsinogen then enters the small intestine through the common bile duct. Enzymes are the catalysts which bind to specific substrates for their actions. Proteolytic enzymes are a type of enzymes which help in the breakdown of proteins. Trypsin, chymotrypsin, erepsin and pepsin are some of the examples.
Therefore, the correct answer is option D.

Note :
Remember that if trypsin enzymes activate from proteolytic cleavage of trypsinogen in the pancreas, then it can lead to a series of events that cause pancreatic self-digestion which means the enzyme trypsin will digest pancreas, which resulting in pancreatitis.
