The lysosome is an organelle that is important to cellular homeostasis through its degradation of different compounds. Degradative enzymes responsible for reactions within the lysosome are most efficient at pH levels below what is found in the cell. What is responsible for allowing a different pH between an organelle and the rest of the cell?

The presence of proton pumps in the lysosome membrane that allows the organelle to maintain higher concentrations of protons.

Explanation:

Lysosomes are known as a membrane-bound cell organelle that is present in many animal cells. They are spherical type vesicles in structure. Lysosomes contain hydrolytic enzymes these enzymes help in the break down of different kinds of biomolecules.

The lysosomal membrane helps to protect the cytosol, and rest of the cells, from the degradative enzymes which are present in the lysosome. They have the ability to maintains their pH by pumping in H+ ions (protons) from the cytosol across the membrane with the help of chloride ion channels and proton pumps.
