The previous statement is true because if a substance cannot get into a cell membrane it is assisted via protein channels however if it doesn't need the protein channels then it just flows through the membrane.
Water is polar. Lipids are non-polar.
The information or message from the DNA out of the nucleus into the cytoplasm, translation the second step from a gene to a protein that takes place in a cytoplasm
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
