Two Forms of Chlorophyll a in vivo with Distinct Photochemical Functions
Abstract
Action spectra of the Emerson effect in Chlorella and Navicula reveal peaks at 670 mμ , in addition to those at 650 mμ (Chlorella) and 630 mμ (Navicula) attributable to chlorophylls b and c. Thus, excitation of chlorophyll a form "chlorophyll a 670" can supplement, in these algae, the excitation of the form "chlorophyll a 680-700." The effect of the auxiliary pigments in these algae may be mediated by energy transfer to "chlorophyll a 670."
