For a cell that must take up ammonia from its environment, will uptake of the charged form require more or less energy than uptake of the uncharged form assuming that the cell has a negative membrane potential? Explain your answer. Drag the terms on the left to the appropriate blanks on the right to complete the sentences Many solutes that must move into and out of cells exist in either a protonated or ionized form, or they have functional groups that can be either protonated or ionized. Simple molecules such as CO2, H3 PO4 (phosphoric acid), and NH3 (ammonia) are in this category, as are organic molecules with carboxylic acid groups, phosphate groups, and/or amino groups Reset Help negatively charged NHg NH4 To say that the cell has a negative membrane potential means that the surface of the plasma membrane has a more negative charge than the surface. A solute such as therefore be drawn inward by the membrane potential, which means that uptake of inner across the plasma membrane wi ill require more energy than the outer uptake of - assuming the same concentration gradient for the two positively charged solutes, of course uncharged
