Match the following correctly
(i) Zymase - (a) Stomach
(ii) Urease - (b) Yeast
(iii) Diastase - (c) Malt
(iv) Pepsin - (d) Soyabean

We need to match each enzyme with its correct source.

(i) Zymase — Found in Yeast (B). Zymase is the enzyme complex in yeast that catalyzes the fermentation of sugars into ethanol and carbon dioxide.

(ii) Urease — Found in Soyabean (D). Urease was first crystallized by James Sumner from jack beans (soyabean family). It catalyzes the hydrolysis of urea.

(iii) Diastase — Found in Malt (C). Diastase is the enzyme found in germinated barley (malt) that converts starch into maltose.

(iv) Pepsin — Found in Stomach (A). Pepsin is a digestive enzyme secreted by the gastric glands in the stomach for protein digestion.

(i)-B; (ii)-D; (iii)-C; (iv)-A

The correct answer is Option A.
