Show full solutionCorrect option: B
Correct answer
BA-III, B-I, C-IV, D-II

Step-by-step explanation

Let's match the enzymes with the corresponding reactions:

  • The enzyme that catalyzes the hydrolysis of sucrose to glucose and fructose is invertase. So, A matches with III.

  • The enzyme that catalyzes the conversion of glucose to ethyl alcohol and CO(_2) (a step in fermentation) is zymase. So, B matches with I.

  • The enzyme that catalyzes the conversion of starch to maltose is diastase. So, C matches with IV.

  • The enzyme that breaks down proteins into amino acids is pepsin. So, D matches with II.

So, the correct option is:

Option B A-III, B-I, C-IV, D-II
