many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
