Active transport mechanisms, including primary and secondary transport, move solutes across the plasma membrane with ATP energy input. The Sodium-potassium pump is a vital example of primary active transport, maintaining ion concentrations for nerve impulse generation and cell function.
Insights
- Active transport mechanisms, such as the sodium-potassium pump, use ATP energy to move solutes against concentration gradients, crucial for maintaining cell function and generating nerve impulses.
- Vesicular transport processes like phagocytosis, pinocytosis, and receptor-mediated endocytosis involve the uptake of materials into cells through vesicles, aiding in nutrient absorption, immune defense, and selective molecule internalization, all requiring ATP energy.
