Question

At which pH lysosomal enzymes remain active?

• A. pH 5
• B. pH 7
• C. pH 8
• D. pH 10

Answer 1

The correct option is A pH 5

Lysosomes contain acid hydrolase enzymes that break down waste materials and cellular debris. They can be described as the stomach of the cell. Lysosomes digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria. The membrane around a lysosome allows the digestive enzymes to work at the pH they require. At pH 5, the lysosomal enzymes remain active and this pH is best suited for enzyme.
