Biology Question on Eukaryotic Cells
Most of hydrolytic enzymes of lysosome function at
A
Acidic pH
B
Alkaline pH
C
Neutral pH
D
Both B and C
Answer
Acidic pH
Explanation
Solution
Lysosomes are small vesicles which are bounded by a single membrane and contain hydrolytic enzymes in the form of minute crystalline or semicrystalline granules of 5-8 nm. The important enzymes are acid phosphatases, sulphatases, proteases, peptidases, nucleases, lipases and carbohydrases. They are also called acid hydrolases because these digestive enzymes usually function in acidic medium or pH of 4-5.
