This is the way that the cell membrane is able to allow material to pass in and out with energy.
- A.
Active transport
- B.
Osmosis
- C.
Passive transport
- D.
Diffusion

What pumps specific solutes to the more concentrated side?
- A.
Active transporters
- B.
Passive transporters
- C.
ATP
- D.
ER
- E.
The nucleus
Correct Answer
A. Active transportersExplanation
Active transporters are responsible for pumping specific solutes to the more concentrated side. Unlike passive transporters, which rely on the concentration gradient to move substances, active transporters require energy, usually in the form of ATP, to move solutes against their concentration gradient. This process allows cells to maintain a higher concentration of certain substances on one side of the membrane, which is essential for various cellular functions. The ER and the nucleus are not directly involved in solute transport, making them incorrect options.Rate this question:
