Primary Vs Secondary Active Transport | Edge |

Many medications work by blocking these transporters. Digoxin (for heart failure) inhibits the Na⁺/K⁺ pump, indirectly raising calcium levels in heart muscle. SGLT2 inhibitors (for diabetes) block secondary glucose transport in the kidneys, causing excess glucose to be excreted in urine.

Both primary and secondary active transport move molecules against their concentration gradients (from low to high concentration). The fundamental difference lies in the . 1. Primary Active Transport primary vs secondary active transport

Secondary active transport, or , does not use ATP directly . Instead, it uses the potential energy stored in an electrochemical gradient —usually one created by a primary active transport system.
