Answer:cells are the basic unit of life!
Explanation:
Channels, when they open, just allow the molecule to pass through. With a pump, it requires energy, and will move it in a certain direction. They move rapidly into the cell via protein molecules.
Mark as brainliest, its ok if you don't mark me
Glad I could help you!
Answer:
C. carrier proteins
Explanation:
The core of the cell membrane is made up of hydrophobic tails of phospholipid. It does not allow the water-soluble material to move across the membrane. Carrier proteins are the membrane proteins that serve as transporters.
The carrier proteins bind the ion or water-soluble molecules and undergo changes in shape. This transports the molecule across the membrane. Carrier proteins serve in passive facilitated diffusion and active transport. The carrier proteins involved in facilitated diffusion transport the molecules down the concentration gradient without any expenditure of energy.
