Which of the following does NOT influence the rate of diffusion of a chemical across a plasma membrane?
A)concentration gradient of the chemical across the membrane B)mass of the diffusing chemical C)distance that the chemical has to diffuse D)amount of ATP available E)temperature
In this type of transport process,a solute (e.g.glucose)binds to a specific carrier protein on one side of the membrane.This binding induces a conformational change in the carrier protein that results in the solute moving down its concentration gradient to the other side of the membrane.
A)osmosis B)primay active transport C)secondary active transport D)facilitated diffusion E)endocytosis
