In A, how would you describe the solution the cells are in? And in B?

Active Transport
• Move solutes against concentration gradient, [L][H]
• Requires energy from ATP (adenosinetriphosphate)
• Example, sodium potassium pump, K+ in and Na+ out

Transport of Large Molecules Across Membranes
Cells rely on:• Exocytosis• Endocytosis
a. phagocytosisb. pinocytosisc. receptor-mediated endocytosis
