Question

proteins that are used only outside the cell are are synthesized in .a. mitochondria .b. rough endolasmic reticulum .c. on smooth e ndoplasmic reticulum .d. free ribosome

Answer 1

The ribosome is used to synthesize the protein in a cell.

However, if the ribosome is present on the outer surface of the Endoplasmic Reticulum then it is known as a Rough ER.

They assemble proteins on the membrane on the ER in a high quantity used as enzymes for the digestion of the tracts or the cells of the pancreas.

Answer 2

Answer:(d) free ribosomes

Explanation:

the function of ribosomes is protein synthesis. Ribosomes can be bound to the ER or can lie free in the cytoplasm. They form polysomes. They synthesise proteins that are to be used outside the cell.
