Question

The force driving simple diffusion is ___, while the energy source for active transport is ___.

Answer 1

Answer:

concentration gradient, ATP

Explanation:

Simple diffusion is a slow movement of components from a region of high concentration to that of low concentration, along the concentration gradient.

Active transport is movement of substances against the concentration gradient which occurs via special proteins at the expenditure of energy in the form of ATP

Answer 2

Answer:

The force driving simple diffusion is the concentration gradient across the membrane, while the energy source for active transport is adenosine triphosphate.
