Question

Lysosome contains

• A. oxidative enzymes
• B. hydrolytic enzymes
• C. reductive enzymes
• D. anabolic enzymes.

Answer 1

Answer: (B)

hydrolytic enzymes

Answer 2

A lysosome is a tiny sac bounded by a single unit membrane of lipoprotein. It contains a dense, finely granular fluid. The latter consists of glycoprotein hydrolytic (digestive) enzymes called acid hydrolases. These include proteases, lipases, nucleases, glycosidases, sulphatases, acid phosphatases, etc. However, all the enzymes do not occur in the same lysosome. There are different sets of enzymes in different lysosomes. The lysosome enzymes can break down all major biological macromolecules present in the cells or entering the cells from outside into their building block subunits by addition of water. The lysosome enzymes are active in acid medium, at about pH 5, hence their name.
