The inside of the cell membrane becomes negative at the time of an action potential.Group startsTrue or FalseTrue, unselectedFalse

If a membrane allows some molecules to pass, it is called semi or differentially _________blank.

Which type of cellular transport moves molecules across the membrane by expending energy?

Molecules move through the plasma membrane in different ways depending on their chemical composition. The semi-permeable nature of the plasma membrane allows some molecules to move through easily, while others require the assistance of a transport protein or cellular energy.What method of transport is used for small, polar molecules?Elimination ToolSelect one answerASimple diffusion.BFacilitated diffusion.CActive transport.DOsmosis.
