More glucose molecules need to enter the cell via active transport. In contrast to passive transport, active transport involves the cell using energy (such as ATP) to move a chemical away from its concentration gradient. There are two types of active transport mechanisms. In primary active transport, molecules are moved across a membrane against their gradient directly using a chemical energy source (such as ATP). Marine fish use their kidneys to conserve water and active transport to transfer solutes out of the cells. In primary active transport, molecules are moved across a membrane against their gradient directly using a chemical energy source (such as ATP). Molecules are moved by secondary active transport by using an electrochemical gradient as an energy source.
