IB Biology - Active Transport
Chapter 1.4 - Membrane Transport
Particles move across membranes by active transport.
Application: Structure and function of sodium–potassium pumps for active transport and potassium channels for facilitated diffusion in axons.
In the previous IB biology article, passive transport is introduced. The diffusion relies on kinetic energy to move the molecules down the concentration gradient. Actually, molecules can go against the gradient by active transport.
Active Transport = molecules move against the concentration gradient with the expense of energy
