Which of the following statements correctly describes some aspect of protein secretion from prokaryotic cells? a. the mechanism of protein secretion in prokaryotes is probably the same as that in eukaryotes. b. proteins secreted by prokaryotes are likely synthesized on ribosomes bound to the cytoplasmic surface of the plasma membrane. c. prokaryotes cannot secrete proteins because they lack rough endoplasmic reticulum. d. prokaryotes cannot secrete proteins because they lack an endomembrane system.

B. Proteins secreted by prokaryotes are synthesized on ribosomes bound to the cytoplasmic surface of the plasma membrane.

Explanation:

Ribosomes, also called ribosomes, are small granule-like structures that are present in prokaryotic and eukaryotic cells. The function of ribosomes is to assist in the production, synthesis and secretion of proteins in cells. That is, the proteins secreted by prokaryotes are probably synthesized on ribosomes attached to the cytoplasmic surface of the plasma membrane.

Ribosomes gather several amino acids during protein synthesis through a chemical bond called a peptide bond.
