You decided to splurge after eating a large dinner by consuming 2 Krispy Kreme donuts. The sugar in your cells is already high from the dinner you ate earlier, but your cells still need to take in the sugar from your blood which is lower. The receptors on your body cells get a message to open a channel in the membrane and allow the sugar into the cell. In which direction will the water move with respect to the cell: either inside the body cell or outside the body cell. EXPLAIN why ENERGY is required for this type of transport, and WHY a protein receptor on the membrane is needed.
