Verified step by step guidance

Understand the concept of simple diffusion: Simple diffusion is a passive transport mechanism where molecules move from an area of higher concentration to an area of lower concentration, driven by the concentration gradient.

Recognize the energy source for active transport: Active transport requires energy to move molecules against their concentration gradient, typically from an area of lower concentration to an area of higher concentration.

Identify the energy source for active transport: The energy for active transport is usually provided by ATP hydrolysis, where ATP (adenosine triphosphate) is converted to ADP (adenosine diphosphate) and inorganic phosphate, releasing energy.

Differentiate between passive and active transport: Passive transport, like simple diffusion, does not require energy, while active transport requires energy input to move substances against their concentration gradient.

Apply the concepts to the problem: The force driving simple diffusion is the concentration gradient, and the energy source for active transport is ATP hydrolysis.
