Can someone please help me with this question!

write a sentence that describes active transport: High concentration, low concentration, gradient, ATP energy, protein pump

Answer 1

In active transport, a protein pump - powered by ATP energy - moves molecules from a low concentration to a high concentration against a concentration gradient

Step-by-step explanation:

Diffusuion is the movement of molecules from a high concentration to a low concentration, and doesn't require energy because it is going with the concentration gradient. To move molecules against a concentration gradient from a low to a high concentration, it requires energy. This is called active transport.
