These categories pertain to different types of transport mechanisms in cells, each with specific characteristics and requirements. Simple diffusion involves the movement of molecules across a membrane without the need for assistance from transport proteins. Facilitated diffusion utilizes transport proteins to aid in the movement of molecules down their concentration gradients. Active transport requires energy (usually in the form of ATP) to pump molecules against their concentration gradients.
