Which of the following is an example of active transport
Posted By Admin @ September 03, 2022
Answer:
Active transport is any process that requires energy to diffuse. Osmosis happens naturally, so this can be ruled out. The transport of glucose can be active (since the molecule is too large to enter a cell naturally), but it can also be passive. To be safe, I'd use the sodium-potassium pump: if I remember correctly, that's always active since ATP must be used for it to happen. I'd check to be sure though. Hope this helps!
