Question

lets find out how much you know about this topic! this will help us personalize your learning experience, and dont worry, it wont affect grades. question 7 of 10 which of the following describes a primary active transport mechanism? an atp - driven pump that uses energy from atp hydrolysis to move ions against their gradient. a channel protein that allows ions to flow down their electrochemical gradient. a carrier protein that transports glucose down its concentration gradient.

Explanation:

Primary active transport uses energy directly from ATP hydrolysis to move substances against their concentration or electrochemical gradient. An ATP - driven pump that moves ions against their gradient is an example of this. A channel protein allowing ions to flow down their electrochemical gradient is passive transport (facilitated diffusion), and a carrier protein transporting glucose down its concentration gradient is also passive transport (facilitated diffusion).

Answer:

An ATP - driven pump that uses energy from ATP hydrolysis to move ions against their gradient.
