Light-Dependent Phosphorylation in Mitochondria

Part of the Biological and Medical Physics Series book series (BIOMEDICAL)


Absorption of light by mitochondrial flavoproteins is accompanied by a number of processes: internal conversion, vibrational relaxation etc. Since the quantum yields of fluorescence and phosphorescence of flavin chromophores in flavoproteins are low [70], the main portion of photoexcitation quanta is transformed to vibronic quanta, i. e to the energy of vibrational and orientational relaxation of protein structure, or, in other words, to a local “heating” of the membrane. This can influence on the rate of oxygen uptake and ATP synthesis.
