By maintaining steep concentration gradients, cells create a form of stored potential energy. Secondary Active Transport and Coupled Movement Not all energy expenditure is direct.
Understanding the Membrane Protein Active Transport Cycle
Because of their central role in physiology, these pumps are prime targets for pharmaceuticals. Quantifying the Work: The Role of Membrane Potential Every movement of charge during active transport alters the electrical potential across the membrane.
Regulation and Pharmacological Targeting The activity of these transporters is tightly regulated to match cellular demands. Neurons rely on the sodium-potassium pump to maintain the resting membrane potential, a prerequisite for nerve impulse transmission.
Membrane Protein Active Transport Cycle and Pump Mechanics
At the molecular level, life is a constant struggle against equilibrium. Cardiac glycosides, such as digoxin, inhibit the sodium-potassium pump to increase the force of heart contractions, demonstrating the clinical relevance of manipulating these pathways.
