Question

going against the flow, the movement of needed molecules from to requires powers active transport, like with the sodium potassium pump. the sodium potassium pump blank 1: blank 2: blank 3: blank 4:

Explanation:

Active transport moves molecules against the concentration gradient, requiring energy. The sodium-potassium pump, shown, transports molecules from intracellular (lower concentration) to extracellular (higher concentration), powered by ATP.

Answer:

Blank 1: intracellular, Blank 2: extracellular, Blank 3: energy, Blank 4: ATP
