Na+ moves from high to low concentration, across the plasma membrane, through a protein channel that is permenantly open. Which statement is true about this process? a. It does not require ATP b. It is a form of active transport c. Movement is against the concentration gradient of Na+ d. The channel probably allows many different molecules and ions to cross
