Each of the Following is an Endoplasmic Reticulum Function Except

Question

Each of the following is an endoplasmic reticulum function except
A)addition of carbohydrate to proteins to make glycoproteins.
B)peptide folding.
C)the assembly of multimeric proteins.
D)the export of protein that cannot be folded into the cytoplasm for destruction.
E)All are endoplasmic reticulum functions.

Accepted Answer

All the options listed are functions of the endoplasmic reticulum (ER). The ER is involved in the modification of proteins (including glycosylation to form glycoproteins), protein folding, the assembly of multimeric proteins, and the identification and export of misfolded proteins for degradation, a process known as ER-associated degradation (ERAD).
