Active Transport

Secondary active transport does not use ATP directly. Instead, it harnesses the potential energy stored in an ion gradient (typically Na⁺ or H⁺) created by primary active transport.

Diabetic drugs (SGLT2 inhibitors like empagliflozin) block glucose reabsorption in the kidney, lowering blood sugar. Proton pump inhibitors (omeprazole) block gastric H⁺/K⁺-ATPase to reduce stomach acid. active transport

For a cell to maintain homeostasis, it must often accumulate high concentrations of specific molecules (like glucose or amino acids) or maintain specific ion balances (like sodium and potassium) that differ from its external environment. This is achieved through specialized transmembrane proteins often referred to as "pumps." Licensed by Google Types of Active Transport Secondary active transport does not use ATP directly

Active transport relies on specialized protein machines embedded in the cell membrane. These aren't just open doors; they are complex engines. The most famous example is the . These aren't just open doors; they are complex engines
