Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A researcher made an interesting observation about a protein made by rough endoplasmic reticulum which is eventually used to build a cell’s membrane. The protein in the membrane was actually slightly different from the protein made in the ER. The protein was probably modified in the ____

A	Golgi body.
B	smooth endoplasmic reticulum.
C	mitochondria.
D	Nucleus.

Explanation:

Detailed explanation-1: -Proteins can be translocated into the ER either during their synthesis on membrane-bound ribosomes (cotranslational translocation) or after their translation has been completed on free ribosomes in the cytosol (posttranslational translocation).

Detailed explanation-2: -The RER in the cell synthesised protein which would be later used in building the plasma membrane. But it is observed that the protein in the membrane is slightly different from the protein made in the RER. The protein was probably modified in another cell organelle.

Detailed explanation-3: -So, the correct answer is ‘Rough ER →→ Golgi apparatus →→ Cell membrane’. Was this answer helpful?

Detailed explanation-4: -This rough endoplasmic reticulum (Rough ER) studded with protein-producing ribosomes is the site of synthesizing proteins destined to export out of the cell.
