Active Transport Need Atp Best — Does

This energy is used to change the shape of transport proteins, often called pumps, located within the cell membrane. A classic example is the sodium-potassium pump. This pump uses ATP to move three sodium ions out of the cell and two potassium ions into the cell. Because both ions are being moved against their respective concentration gradients, the direct chemical energy from ATP is required to force the protein carrier to function. Without ATP, these vital gradients would collapse, leading to cellular dysfunction or death. Secondary Active Transport and Indirect Energy Use

While all active transport requires energy, the way ATP is used can vary. There are two main categories: does active transport need atp
