Question

how do cells use energy to move substances that cannot diffuse across a membrane.

Answer 1

Answer:

-half 4 y? 2 y minus 5 x minus one-half 2 y 2 x Negative 2 x minus one-half 6 y 3 x Negative 3 x minus three-fourths 4 y one-fourth Negative

Answer 2

Answer:

Moving Against a Gradient

Explanation:

To move substances against a concentration (or electrochemical gradient), the cell must use energy. The energy is gathered from adenosine triphosphate (ATP) generated through the cell's metabolism. Active transport mechanisms, called pumps, work against electrochemical gradients. Hope this helps!
