Movement of substances can be classified as active transport of passive transport.
In passive transport movement of substances across the membrane occurs without the expense of ATP. It occurs usually along the concentration gradient i.e., from high concentration to low concentration.
In active transport, movement of substances require energy in the form of ATP because it happens against the concentration gradient i.e. from low concentration to high concentration.
