Lysosome Structure and Function | Class 11 Biology Explained

[00:00:00]Class 11 lysosome structure. Lysosome is single membrane bound. Lysosome membrane is stabilized by sterols or cholesterol.

[00:00:11]And lysosome membrane has proton pumps that opens when it fuses with the food vacuole.

[00:00:19]And the proton pump drives proton from cytoplasm into the lysosome vesicle and makes the medium acidic so that the acid hydrolytic enzymes in the primary lysosome becomes active. Okay?

[00:00:34]So, lysosomal enzymes become active in acidic medium and that is due to opening of proton pump on the lysosomal membrane.
