What is responsible for the low pH found in lysosomes?

1Fusion of vesicles with a low pH to the lysosome.
2The lack of oxygen available in the lysosome.
3 The lack of sulfatases in the lysosome.
4The excess protons in the lysosome that have been pumped in by a proton pump.

Answer #1

Lysosomes contain hydrolytic enzymes which can break down protein, carbohydrate and lipids. These enzymes need a low pH for their activation. This low pH is maintained inside lysosones by help of pumping excess prtons inside lysosones by proton pump.

Option 4 is correct.
