is
hydrolyzed and the phosphate group is transferred we call it
phosphorylation.
In review, substances cross the cell membrane in two different ways:
passive and active transport. Passive transport includes osmosis,
diffusion, and facilitated diffusion. None of these techniques use
energy. Active transport includes endo and exocytosis, sodium-potassium
pumps. and phosphorylation, all of which expend energy to transport
substances across the cell membrane. The cell has the ability to
regulate what crosses its cellular boundaries.
