Web5 de mai. de 2024 · Active transport may be primary or secondary.A primary active transport is one that uses chemical energy in the form of ATP whereas a secondary active transport uses potential energy often …
WebQuestion 7. 45 seconds. Q. How does the amount of cellular energy used to move a molecule into a cell by active transport compare to the energy used for its movement … WebWhy is it active transport? Because we're using ATP to drive sodium against its concentration gradient to keep pumping the sodium out of the cell, and then potassium kind of comes in, you could almost imagine, passively. It doesn't require ATP. And that's why this is often called a sodium-potassium ATPase, which means it's a protein or an ...

Web23 de jul. de 2024 · Root hair cells Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
WebPlant and bacterial cells usually use hydrogen ions as the driving substrate; sugars and amino acids are the most common driven substrates. When the bacterium Escherichia coli must metabolize lactose, it co-transports hydrogen ions with lactose (which can reach a concentration 1,000 times higher than that outside the cell).
