The outward movement of protons (H+),

Which of the following regarding the sodium potassium pump is FALSE?   It tends to be found on the apical plasma membrane of polarized cells It transports three sodium ions to the outside of the cell It transports two potassium ions to the inside of the cell. It helps to maintain unequal distribution of ions across the plasma membrane

Without saturation of transport proteins and under the same concentration gradient how can the speed of simple diffusion be compared to the speed of facilitated diffusion?

Select the correct statments regarding transport of molecules across the cell membrane.     Non-mediated transport is susceptible to saturation of transporter/channel proteins.     Channels and transporters need not use energy to transport solute down the concentration gradient.     The Na+/K+ antiport takes advantage of electrochemical gradients to exchange Na+ and K+ ions across the cell membrane.     Active transport via electrochemical gradients relies on the passive transport of one solute to transport a second solute against the concentration gradient. Describe the three main sources of membrane fluidity
