Choose the item in column 2 that best matches each item in column 1.

Question

A) diffusion and passive and active transport
B) both passive and active transport
C) diffusion
D) active transport
E) none of the listed processes
F) both diffusion and passive transport
G) indirect active transport
H) passive transport

1) requires a specific integral membrane protein
2) dependent on solubility properties of the solute
3) requires cellular expenditure of energy
4) Keq = 1
5) Na+/glucose symport
6) Na+/K+ pump
7) exclusively involves the transfer of small, nonpolar molecules
8) applies only to ions
9) ?G° = 0
10) direction of transport is dependent upon the concentration gradient at any given point in time
11) requires ligand binding and therefore Michaelis constants can be calculated
