Which of the following functional differences between the rough and smooth endoplasmic reticulum ( ER) is explained by the strictural differences between them?
(A) Rough ER breaks down toxic substances, and smooth ER only transports them out of the cell.
(B) Rough ER can synthesize and package lipids for export, and smooth ER cannot.
(C) Rough ER can produce ATP, and smooth ER cannot.
(D) Rough ER can synthesize and package proteins for export, and smooth ER cannot.

Question

Accepted Answer

***D*** ∻Key Concept∻ ⚹Rough ER synthesizes and packages proteins⚹ ∻Explanation∻ ⚹The rough ER is studded with ribosomes, which are essential for protein synthesis. These proteins are then packaged for export. The smooth ER, lacking ribosomes, is involved in lipid synthesis and detoxification processes.⚹◊How do the structural differences between rough and smooth endoplasmic reticulum contribute to their functional differences in protein synthesis and packaging?⍭ Generate me a similar question◊
