• 76-79 Abstract--Researchers are conducting measurements of harmonics generated by biological systems in response to applied sinusoidal electric fields. The frequency and amplitude-dependence of the induced harmonics exhibit features that correlate with physiological processes. For example, budding yeast cells (S. cerevisiae) produce numerous harmonics, the amplitudes of which depend strongly on frequency. Thus far, we have observed harmonics that appear to be generated by active molecular motors, such as membrane pumps, in the plasma membrane and in internal organelles, including mitochondria and chloroplasts (for plant cells). |
