Quizplus · Accepted Answer

Degrading cellular proteins is necessary for the cell to eliminate incorrectly folded or damaged proteins to maintain protein homeostasis. It is also needed to remove specific enzymes and plasma membrane proteins during cellular processes such as cell division or differentiation. The tight control of the cell cycle also involves the degradation of specific proteins at different stages to ensure proper progression.
