Detailed explanation-1: -Lysosomes function as the digestive system of the cell, serving both to degrade material taken up from outside the cell and to digest obsolete components of the cell itself.
Detailed explanation-2: -Lysosomes contain portions of cytoplasmic components such as glycogen, mitochondria, or cisternae of the endoplasmic reticulum. Hydrolytic enzymes (phosphatases and proteases) provide intracellular digestion of worn-out cellular organelles and materials taken into the cell by endocytosis.
Detailed explanation-3: -When food is eaten or absorbed by the cell, the lysosome releases its enzymes to break down complex molecules including sugars and proteins into usable energy needed by the cell to survive. If no food is provided, the lysosome’s enzymes digest other organelles within the cell in order to obtain the necessary nutrients.
