The force driving simple diffusion is a concentration gradient, while the energy source for active transport is ATP hydrolysis.Group of answer choicesFalseTrue

The statement is True.

Explanation:

1. Simple Diffusion and Concentration Gradient: Simple diffusion is a process where molecules move from an area of higher concentration to an area of lower concentration without the need for energy input. This movement is driven by the concentration gradient, which seeks to equalize concentrations on either side of a membrane.

2. Active Transport and Energy Source: Active transport is a process that requires energy to move molecules against their concentration gradient, meaning from an area of lower concentration to an area of higher concentration. The primary energy source for this process is the hydrolysis of ATP (adenosine triphosphate), which provides the necessary energy for transport proteins to function.

Thus, both parts of the statement accurately describe the mechanisms of simple diffusion and active transport, confirming that the entire statement is true.
