Final answer:
Enzymes protect the cell membrane from being catabolized by regulating metabolic pathways and controlling biochemical reactions.
Step-by-step explanation:
What protects the cell membrane from being catabolized? The components of the cell membrane include lipids, proteins, and carbohydrates, which play various roles in its structure and function. Enzymes protect the cell membrane by regulating metabolic pathways and preventing the unintentional catabolism of the membrane. Therefore, among the given options, enzymes are the most direct contributors to the prevention of cell membrane catabolization by facilitating and controlling biochemical reactions, including those that could potentially damage the membrane components.
