Modifies protein.
The Golgi body.
a protein is too big to enter a cell on its own, therefore it requires carriers in order to do so. the carriers transport the protein in/out of the cell.
There are glucose transport proteins. Since there are fewer glucose particles in the cell (when compared to the fluid outside of cells), it is passive transport, which occurs naturally. The transport protein is necessary for the glucose to pass through the cell membrane.
Active transport
it produces protein for the cell
carrier protein
It requires energy, and a carrier protein. The large particle binds to the carrier protein on the inside of the cell. The protein then changes conformation, thus moving the particle to the outside, where it is dropped off by another conformational change in the protein.
The "Protein Factories" in the cell are known as Ribsome.
Embedded in the semi-permeable cell membrane are many different types of carrier proteins or channel proteins. These globular proteins allow the transport of specific substances from the outside of the cell into the cell or vice versa.Specific means each protein can only transport one type of substance across. For example, Protein A can transport Substance X but not Substance Y. Substance Y has to be transported by Protein B which cannot transport Substance X. The specific nature of these globular proteins mean it is easier for these molecules to be transported.
A vesicle is a small membrane-enclosed sac that can store or transport substances. So basically they help transport the protein.
