A typical root pumps out H⁺ to maintain a strong membrane potential of about

Question

Quizplus · Accepted Answer

The answer is the option that mentions membrane potential, which is D. The membrane potential of a cell is usually negative, meaning that the inside of the cell has a more negative charge with respect to the extracellular fluid. The value of the membrane potential varies among different types of cells, but a typical value for animal cells is around -70 mV. Therefore, option D, which indicates a membrane potential of -160 mV, could be a plausible value, especially for a root cell that needs to maintain a strong gradient to absorb nutrients and water from the soil. The other options are not related to membrane potential and are incorrect in this context.
