Question 59

Matching

Choose the item that best matches the other items.

Premises:
Na+/K+ pump
applies only to ions
exclusively involves the transfer of small, nonpolar molecules
Keq = 1
ΔG° = 0
direction of transport is dependent upon the concentration gradient at any given point in time
requires ligand binding and therefore Michaelis constants can be calculated
requires cellular expenditure of energy
dependent on solubility properties of the solute
Na+/glucose symport
requires a specific integral membrane protein
Responses:
none of the listed processes
diffusion
both diffusion and passive transport
active transport
diffusion and passive and active transport
passive transport
both passive and active transport
indirect active transport
