Question

Lysosomes maintain an acidic environment by actively pumping protons into their interior.

Accepted Answer

Lysosomes maintain an acidic environment with a pH of around 4.5 by actively pumping protons (H+) into their interior using proton pumps such as the vacuolar ATPase. This acidic environment is necessary for lysosomal enzymes to function optimally and break down various biomolecules.
