The Na⁺/K⁺ pump restores resting membrane potential after an action potential. Inhibition (e.g., by ouabain) stops nerve signaling.
Active transport is the boundary between chemistry and life. Chemistry is the passive drift toward equilibrium. Life is the active resistance against it.
The substances move in opposite directions (e.g., the sodium-calcium exchanger). Bulk Transport: Endocytosis and Exocytosis active transport
There are several types of active transport mechanisms, including:
Active transport is essential for various cellular processes, including: Chemistry is the passive drift toward equilibrium

Active transport is expensive. While passive transport is free, active transport can consume up to a resting cell produces. Bulk Transport: Endocytosis and Exocytosis There are several
Secondary active transport does not use ATP directly. Instead, it uses the electrochemical gradient established by primary active transport as an energy source. When one substance moves down its concentration gradient (e.g., sodium moving back into the cell), it "hitches a ride" for another substance moving against its gradient.
The mechanisms of active transport involve a series of complex steps, including:
A defective CFTR chloride channel (an ABC transporter, a form of primary active transport) leads to thick mucus in lungs and pancreas.
