AP Biology Short Distance of Transport in Plants 1) Proton Pumps – Figure 1 a) Proton pumps pump hydrogen ions out of the cell with an input of energy (ATP) b) This charge difference is called membrane potential; it can be used to drive the transport of other solutes 2) Solute Transports in Plants – Figure 2 a) Membrane Potential and Cation Intake Cations are driven into the cell by the membrane potential (from positive concentration and low concentration): Passive transport

Unformatted text preview: b) Cotransport of an anion with hydrogen ions Anions are coupled with hydrogen ions and they are both transported at the same time by cotransporter (symport) Secondary Active Transport = The process in which anions that come with other ions c) Cotransport of a neutral solute with hydrogen ions Other neutral solutes can also come in with hydrogen ions by cotransport mechanism <Figure 1> Proton Pumps <Figure 2> Solute Transport In Plants...
