As one ion (usually sodium) flows down its concentration gradient, the energy released is used to pull another molecule up its own gradient. Types of Secondary Active Transport

) into the cell. This creates the electrical and chemical gradients essential for nerve impulses and muscle contractions. What is Secondary Active Transport? Think of primary active transport as a pump

One cannot exist without the other. Primary transport builds the hill; secondary transport rolls the boulder down the hill to do work. Together, they power the chemistry of life. they power the chemistry of life.
