1 Active Transportï§ Active Transport requires the cell to use energy, usually in the form of ATP.ï§ Active Transport creates a charge gradient in the cell membrane. 2  For example in the mitochondrion, hydrogen ion pumps pump hydrogen ions into the intermembrane space of the organelle as part of making ATP. 3  15.
Passive Transport. Passive transport is the cellular process of moving molecules and other substances across membranes. Passive transport differs from active transport in that it does not involve any chemical energy.Rather, passive transport relies on the innate permeability of the cell membrane and its component proteins and lipids.There are four main types of passive transport:assive transport differs from active transport in that it does not involve any chemical energy.
