Question

Which best describes functions of the smooth (agranular) endoplasmic reticulum?
A)Transcription of DNA into RNA
B)Generation of ATP
C)Digestion of engulfed bacteria and cellular debris
D)Synthesis and packaging of proteins for secretion from the cell or export to other organelles
E)Synthesis of lipids and intracellular storage of calcium ions

Quizplus · Accepted Answer

The smooth endoplasmic reticulum is responsible for the synthesis of lipids and the storage of calcium ions within the cell. It is not involved in transcription, generation of ATP, or digestion of engulfed bacteria and cellular debris. While the rough endoplasmic reticulum is responsible for the synthesis and packaging of proteins for secretion from the cell or export to other organelles.
