Question

Quizplus · Accepted Answer

Lysosomes have an acidic environment (lower pH) due to a higher concentration of protons, achieved by proton pumps in their membranes. They fuse with vesicles containing macromolecules for degradation and their membranes transport breakdown products into the cytoplasm.
