When sodium chloride (NaCl) moves across a cell membrane, it typically travels through a protein channel and moves from high concentration to low concentration. Compared to the models of protein transport, which model best matches this description and why is a protein channel necessary?

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

i'm assuming that it's c.) red bank..

consider the reaction below.

 no rx

at 500 k, the reaction is at equilibrium with the following concentrations.

[pci5]= 0.0095 m

[pci3] = 0.020

[ci2] = 0.020 m

what is the equilibrium constant for the given reaction?

0.042
