Time Course and Quantum Efficiency of Photosynthesis in Chlorella
1. Though the quantum yield remains constant for different samples of the same culture despite great changes in respiration due to dark adaptation, the quantum requirement for different cultures varies from 6.1 to 13.5 quanta per molecule of oxygen evolved (q/m). 2. This variation from one culture to another appears to depend upon chlorophyll concentration, though other paralleling factors cann...
متن کاملOzone Inhibition of Photosynthesis in Chlorella sorokiniana.
Exposure of Chlorella sorokiniana (07-11-05) to ozone inhibits photosynthesis. In this study, the effects of ozone on O(2) evolution and fluorescence yields are used to characterize this inhibition. At an ozone dose of about 3 micromoles delivered to 2 x 10(9) cells, the photosynthetic rate of the cells is inhibited 50%, as indicated by a decrease in bicarbonate-stimulated O(2) evolution (contr...
متن کاملMaximum quantum yield and action spectrum of photosynthesis and fluorescence in Chlorella.
The maximum yield of oxygen production in Chlorella was found, in new, systematic experiments, not to exceed o.12, under a great variety of conditions. Measurements were made on autospores and other synchronous cultures, at different CO~ concentrations, at very low light intensities, and in the presence of 'catalytic ' amounts of blue light. The action spectra (quantum yield as a function of wa...
متن کاملRespiration and Intensity Dependence of Photosynthesis in Chlorella
1. Respiration changes as a result of illumination. 2. In the absence of glucose or other supply of substrate, respiration decays in the dark showing at least two types-a fast decay in a few minutes and a slow decay lasting hours. 3. Respiratory response to illumination is delayed. 4. Intermittent illumination (in the absence of glucose, etc.) produces a periodic variation in respiration with a...
متن کاملPhotorespiration and Oxygen Inhibition of Photosynthesis in Chlorella pyrenoidosa.
The inhibition of photosynthesis by O(2) in air-grown Chlorella pyrenoidosa was investigated using three experimental techniques (artificial leaf, aqueous method, and O(2) electrode) to measure carbon assimilation. CO(2) response curves were determined under different O(2), pH, and temperature conditions. Regardless of the experimental technique and condition, O(2) inhibition was not evident un...
