1. In Chroococcus a quantum of light absorbed by phycocyanin has 90 per cent the chance of doing photosynthesis that a quantum absorbed by chlorophyll has. 2. By a process analogous to internal conversion in radioactivity (but with the linear dimensions and the wave length 10(4) times larger) there will be transferred from phycocyanin to chlorophyll See PDF for Equation (a number of the order of 100) quanta for every one emitted as fluorescent light by the phycocyanin in the Chroococcus cell. 3. The yield of fluorescent light in Chroococcus is between 1 and 2 per cent. 4. The transfer of energy by internal conversion can account for the photosynthesis by phycocyanin observed by Emerson and Lewis. |
