Web20 okt. 2024 · A molecular pump is a protein that moves ions or solutes across a concentration gradient. Through the use of molecules, an electrochemical gradient across the membrane can generate a membrane potential. The sodium-potassium pump, ATP synthase, and other molecular pumps are some of the most well-known. WebFigure 5.17 Proton Gradient provides energy for a secondary active transporter. The proton pump creates an electrochemical gradient of protons (hydrogen ions, H+) using ATP to drive primary active transport. This gradient allows for cotransport/secondary transport of sucrose against its concentration gradient as protons come down their concentration …
