If a plant physiologist is studying the mechanism by which minerals are taken in by the roots,that would be a study of what?

Question

Quizplus · Accepted Answer

Plant cells expend energy to actively take up and concentrate mineral ions.A proton pump hydrolyzes ATP and uses the energy released to transport hydrogen ions (H+)out of the cell.This sets up an electrochemical gradient.The electrochemical gradient then drives positively charged ions such as K+ through a channel protein into the cell.Negatively charged mineral ions are transported,along with H+,by carrier proteins.Since H+ is moving down its concentration gradient,no energy is required.
