Contributions to the electrochemistry of the cell



Evidence is presented in this report which (1) directly establishes the fact of a quantitative relation between cell oxidations and electric polarity in the root tip of the onion Allium cepa, (2) demonstrates that an unequal change in electric polarity is produced by equal changes in oxygen concentration around different regions of the root tip, (3) shows that the characteristic pattern of distribution of E. M. F. per unit length is modified by changes in oxygen concentration, (4) indicates that the velocity of oxidations is greatest in the cells actively engaged in cell multiplication, and (5) presents direct evidence for the flux equilibrium theory of bioelectric potentials
