Active Transport
1. What is Active Transport with Example?
Active transport is a cellular process that requires energy to move molecules or ions against their concentration gradients, as seen in the sodium-potassium pump (Na+/K+ pump) in cell membranes.
2. What are 3 Types of Active Transport?
The three types of active transport are:
- primary active transport,
- symport secondary active transport,
- antiport secondary active transport.
3. How is ATP used in Active Transport?
ATP is used in active transport that provides the energy to the transport protein that enable it to pump molecules or ions against their concentration gradients. This energy allows these proteins to actively transport substances, such as sodium and potassium ions, across cell membranes.
4. Why is Active Transport Important?
Active transport is essential for maintaining specific cellular conditions by regulating ion concentrations, enabling nutrient uptake, and facilitating various physiological processes, such as nerve impulse transmission. It ensures proper cell function and homeostasis.
5. What are the Uses of Active Transport?
Active transport is used to maintain vital ion gradients in nerve cells, facilitate nutrient absorption in the digestive system, regulate cell volume, and remove waste products and toxins from cells, ensuring proper cellular function and homeostasis.
Active Transport
Active transport is a cellular process that uses energy mainly in the form of ATP, to move molecules or ions against their concentration gradients. It includes primary active transport, which directly uses energy for transport, and secondary active transport, which utilizes an electrochemical gradient to move other substances. It is essential for many physiological processes, including nutrient absorption in the digestive system, the transmission of nerve impulses, and the regulation of ion concentrations in cells.
