Passive vs. active transport

Passive vs. active transport

Passive vs. active transport. Passive transport is simply transport down an electrochemical gradient until equilibrium is reached Active transport results in accumulation of solute beyond equilibrium, the unfavorable thermodynamics is driven by ATP hydrolysis. Passive vs. facilitated diffusion.
