Which of the following combinations is most likely to result in digestion?

a. pepsin, protein, water, body temperature

b. pepsi, protein, water, body temperature, HCl (hydrochloric acid)

Explain.

Option (b).

Explanation:

Digestion may be defined as the process of break down of large food particles into simpler substances that be absorbed by the body. Specific enzymes are required for the breakdown of specific chemicals.

The combination that contains protein, water, HCl (hydrochloric acid), temperature and pepsin result in digestion. HCl (hydrochloric acid) activates the enzyme pepsinogen into pepsin. The pepsin than digest the proteinsat the body temperature in presence of water. Proteins are broken down into simple amino acids that can be seen as a result of digestion.

Thus, the correct answer is option (b).
