Function Of Transport Protein

Penny, an Active Transport protein, smiled. She was built differently than Trevor. She had a binding site for a tiny, high-energy battery called .

Transport proteins also play a major role in secondary active transport, also known as cotransport. In this process, a transport protein uses the energy from an existing gradient—like the sodium gradient created by the Sodium-Potassium Pump—to move a second substance against its own gradient. For example, in the human gut, transport proteins use the flow of sodium ions into the cell to "pull" glucose along with them. This allows the body to maximize nutrient absorption even when glucose levels inside the cells are already high. function of transport protein
