Physiology Quiz - General Principles of Membrane Transport - Part 2
Transport of ions and molecules across biological membranes may occur by passive or active mechanisms and, indeed, membrane transport mechanisms form the basis for many important physiological processes. Test your basic knowledge of membrane transport by taking this simple quiz.
(1) Which of the following can permeate (i.e., cross) a pure lipid bilayer?
(2) In general, secondary active transporters cannot perform their normal function without the necessary concentration gradients established by primary active transporters.
