(ii Fill in the blanks below6 marks Active transport is the movement of molecules and ions their concentration gradients, from concentrations. This transport requires the expenditure of in the form of If a cell is poisoned with cyanide (which inhibits oxidative phosphorylation), active transport will iii) Two solutions with different osmolarities are separated by a water- permeable membrane. In the space provided below describe why a change in the volumes of the two compartments will occur if the membrane is impermeable to the solutes, but no change in volume will occur if the membrane is permeable to the solutes? (6 marks) (iv Fill in the blanks below (5 marks) In a resting neuron, there is accumulation of charge on the inner surface of the cell membrane. The typical neuronal resting membrane potential (RMP measures approximately transporting three transporting two .The Na/K pump operates by ions out of the cell while ions into the cell. -gated ion channels open or close
