Answer:
The answer for this question D
Explanation:
To move substances against a concentration or an electrochemical gradient, the cell must use energy. This energy is harvested from ATP that is generated through cellular metabolism. Active transport mechanisms, collectively called pumps or carrier proteins, work against electrochemical gradients. Hope this helped :)
Answer:
A
Explanation:
Channel and carrier proteins are both considered facilitated diffusion. We also know that materials do not like to go against the concentration gradient so we can eliminate B.
Answer:it will act as a defusion or a reaction
Explanation:
Selectivity permeable membrane and a scaffold for biochemical activity
