What is the site of synthesis of proteins for export secretion from the cell)?
A) ribosomes that attach to the endoplasmic reticulum
B) ribosomes that attach to the Golgi complex

D) free ribosomes

Question

Quizplus · Accepted Answer

Proteins that are destined for export or secretion are synthesized by ribosomes that attach to the endoplasmic reticulum, where they are then processed and transported through the Golgi complex before being secreted from the cell. Free ribosomes are involved in the synthesis of proteins that are localized within the cytoplasm or nucleus of the cell. Ribosomes that attach to the outer mitochondrial membrane are involved in the synthesis of proteins that are targeted to the mitochondria.
