In endocytosis, the plasma membrane pinches in, forming a vesicle that contains material from outside the cell. How do materials enter and leave cells? The sodium-potassium pump moves ions against their concentration gradient, from where they are less concentrated to where they are more concentrated. c oxygen Direct link to Matt B's post Careful: it moves from HI, Posted 5 years ago. hypertonic lost water, Part D True or false? Hint 1. c) ATP (adenosine triphosphate); The hydrolysis of ATP provides the energy needed for an endergonic reaction.
