NEET BIOLOGY

Detailed explanation-1: -Definition. A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts.

Detailed explanation-2: -As most high schoolers learn, the lysosome carries out waste disposal and recycling. In a process known as autophagy (meaning “self-eating”), it takes in old cellular components and unneeded large molecules, such as proteins, nucleic acids and sugars, and digests them with the help of enzymes and acids.

Detailed explanation-3: -(Otherwise, if a lysosome were to leak or burst, the enzymes could kill everything in the cell.) When a lysosome comes across cellular debris it can’t reuse, it fuses with the cell membrane and dumps the waste out of the cell in a process called exocytosis.
