Cells can have two kinds of endoplasmic reticulum (ER) : smooth ER, which has no

ribosomes, and rough ER, which has ribosomes embedded in its membrane. What

would happen if the rough endoplasmic reticulum in the cell of an organism lost all

of its ribosomes?

A. ATP production in the cell would stop.

B. Protein production in the organism would stop.

C. Storage of proteins within the cell would increase.

D. Proteins would no longer be exported from the cell.

Answer: B. Protein production in the organism would stop.

Explanation: Ribosomes are organelles involved with synthesis of proteins. There are about 10 million ribosomes in a single cell. Therefore, absence of ribosomes would result lack of protein production by the cells or ER.
