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 :)
The South African economy can be most accurately be described as a mixed market economy. South Africa is a technologically advanced market economy. It has one of the strongest economies in Africa. They produced textiles, chemicals, iron and fertilizer.
