Indicate the direction of net movement Indicate the solute(s) for which the movement across the membrane will be oppositely influenced by the membrane potential and the concentration gradient. Explain how j Indicate the solute for which the movement into the cell will have the most negative free energy change.

Explanation / Answer

a. solutes that enter the cell without the need of a membrane protein

b. Solutes that can readily enter the cell by simple diffusion

c. Solutes entering the cell by facilitated diffusion

d. Solutes for which movement across the membrane will not be influenced by the membrane potential

e. Solutes that can readily enter the cell by channel proteins mediated facilitated diffusion

f. Solutes that can readily enter the cell by carrier protein-mediated facilitated diffusion

g. Solute that can only enter the cell by active transport
