Question

suppose a cells membrane breaks down, but there are not enough materials for its repair. damage to which of the following structures is most likely the cause? smooth endoplasmic reticulum lysosomes rough endoplasmic reticulum mitochondria

Explanation:

The smooth endoplasmic reticulum is involved in lipid synthesis. Cell - membranes are composed mainly of lipids. If there are not enough materials for membrane repair, damage to the smooth endoplasmic reticulum is most likely the cause as it is responsible for producing the lipid - based components of the membrane. Lysosomes are for digestion of waste, rough endoplasmic reticulum is related to protein synthesis, and mitochondria are the power - houses of the cell.

Answer:

Smooth endoplasmic reticulum
