Distinguish between primary and secondary lysosomes; how do they function?

What will be an ideal response?


Primary lysosomes contain inactive enzymes; activation of these enzymes occurs when the lysosome fuses with the membrane of damaged organelles. This forms a secondary lysosome, which contains activated enzymes that act to break down the engulfed contents. These contents then either reenter the cytosol (if nutrients) or are eliminated by exocytosis (if toxins or wastes).
