    C)  glyoxisomes      

    D)  peroxisomes.

    Correct Answer: B

    Solution :

    : Lysosomes contain about 30 different kinds of powerful hydrolytic digestive enzymes. These are proteases, ribonucleases, deoxyribonucleases, phosphatases, cathepsin, glycosidases and sulphatases. Most of these enzymes are more active in acidic pH. The lysosome membrane is impermeable to the digestive enzymes stored within it and capable of withstanding their digestive action against macromolecules within the cell.
