Consider the transport scenario shown. Which curve represents the overall movement of the small molecule from the extracellular environment to the cytosol?

Question

Quizplus · Accepted Answer

Curve C represents the overall movement of the small molecule from the extracellular environment to the cytosol. It starts at a high concentration outside the cell and decreases as it moves through the membrane, eventually reaching a low concentration in the cytosol. Curve A represents the movement of the small molecule into the membrane but does not show its movement into the cytosol. Curve B shows the movement of a large molecule into the membrane and Curve D shows the movement of a small molecule out of the cytosol.
