Question

Which groups of organelles is directly responsible for the production of new molecules within a cell?

A) ribosomes, the endoplasmic reticulum, and Golgi apparatuses
B)Golgi apparatuses,lysosomes, and the plasma membrane
C) the endoplasmic reticulum, plastids, and vacuous
D) the nucleolus,vacuoles, and ribosomes

Answer 1

Hi, it has to be a.):
The ribosomes are RNA-protein complexes that carry out the protein synthesis in cells
The rough endoplasmis reticulum is covered with ribosomes, which produce membrane proteins and proteins for secretion. The smooth ER is involved in the production of lipids, such as phospholipids for the membranes.
In the Golgi apparatus, the proteins get posttranslationally modificated by adding oligosaccharides to them(glycosylation), this oligosaccharides get assembled there, so this probably counts as producing new molecules
