active ion transport造句

• Based on this phenotype, Chop1 could be assigned to TC category # 1 . A, but because it belongs to a family in which well-characterized homologues catalyze active ion transport, it is assigned to the MR family.
• His demonstration ( in 1972 ) that the most important transport system in the plasmalemma of Characean cells is a proton-pumping ATPase, generating membrane potentials well negative of the potassium equilibrium potential, was a major advance & Previously plant physiologists had assumed that plant cells were like animal cells, with an ATP-dependent sodium-potassium exchange pump as the major process of active ion transport.
