A)in the cytoplasm by free ribosomes.
B)by ribosomes in the nucleus.
C)by ribosomes bound to the rough endoplasmic reticulum.

Question

Quizplus · Accepted Answer

Integral membrane proteins are synthesized by ribosomes bound to the rough endoplasmic reticulum, which is responsible for protein sorting and membrane synthesis. In Paramecium, this is where the cell surface integral membrane proteins would be synthesized.
