Unformatted text preview: ing sites Saturable Active Transport Primary Active Transport Energy comes from a high energy compound Energy is usually from ATP hydrolysis E.g.: Na/K pump This is the sodium/potassium ATPase pump. Creates the sodium/potassium gradient. This pump will bind 3 Na+ Picks up the phosphate from ATP, opens and distributes Na+ on the other side of the membrane. 2 K+ bind to protein, phosphate falls off, the potassium is released on the original side of the membrane. Active Transport: Secondary Active Transport Energy is released from ion diffusion Energy drives a pump Diffusion result of prior active ion transport One of the pumps that will bring glucose into the cell is activated by sodium being brought into the cell, the glucose is also brought along. Here, the sodiu...
