Direct hydrolysis of ATP (or other high-energy molecules like light in photosynthesis). what are the 2 major types of active transport
Found in nearly all animal cell membranes, this pump moves: | | Primary Active Transport | Secondary Active
Active transport is a fundamental biological process essential for cellular life. Unlike passive transport (e.g., diffusion, osmosis), which moves substances down their concentration gradient without energy expenditure, This process requires energy, typically in the form of ATP (adenosine triphosphate). Proton Pump | Sodium-Glucose Cotransporter
