The Na⁺/K⁺ pump restores resting membrane potential after an action potential. Inhibition (e.g., by ouabain) stops nerve signaling.

SGLT1 in the small intestine absorbs dietary glucose. Patients with mutations in SGLT1 suffer from severe glucose-galactose malabsorption. 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
