The active transport of na + and solute molecules depends on the proton electrochemical gradients established by proton pumps Na ~ +和可溶性物质的次级转运依赖于由质子泵建立的质子电化学梯度。
Na + / h + antiporter is one sort of protein which on the membrane or vacuole membrane , they can transport na + retrorsely out of the cell or into the vacuole . most of the algaes and the salt plants have this kind of protein Na ~ + h ~ +运输蛋白是位于质膜和液泡上的一类运输蛋白,它可以逆电化学梯度将na ~ +排出细胞外或区隔化于液泡中,普遍存在于藻类与盐生植物中。
Pcr analysis indicated that all lines had been integrated of ssmapkk . northern analysis revealed the presence of expression of ssmapkk mrna in transgenic lines . in principle , ssvp overexpression can increase proton electrochemical gradients across the vacuolar membranes , which permit the secondary active transport of na + and solute molecules 理论上, ssop的过量表达可增加转基因植株细胞跨液泡膜的质子电化学梯度,为次级转运提供驱动力,从而增加可溶性物质和na十向液泡内的转运,提高转基因植株的抗旱和抗盐性。
It is including the structure of neurons , the distribution of ions concentration in or out of the neuron membrane , the electrochemical gradient of ions , the equilibrium potential , the resting potential and action potential of neuron , the ion theory of the transmembrane potential and the hodgkin - huxley ( hh ) equation 包括神经元的结构,神经元细胞膜两边离子浓度的分布,离子的电化学梯度和平衡电位,神经元的静息电位,动作电位,描述神经元膜两边电压变化的离子学说以及hodgkin - huxley方程。
