Document Summary
Endomembrane is what allows the cell to form compartments. Has pores in its membrane so that nutrients can pass through. Cylindrical proteins (are the pores) open to let mrna out, can only open with energy. Contains the nucleolus responsible for assembling ribosomes, an area rich in rrna (ribosomal rna) Translation occurs in ribosomes attached to the membrane. Made up of large and small subunits. Rough er has ribosomes studded along its surface, smooth er does not. This means you can produce a lot of protein at the same time. Smooth er creates lipids, detoxifies the cell (awesome at detoxifying alcohol) This is going to affect how it travels inside or outside the cell, how it interacts with other proteins. Looks like stacks of membrane folds, like flattened pancakes. Makes sure that the proteins are addressed properly. Can digest components from outside the cell. It"s like a cell within a cell.
