Temperature and photosynthesis 1. Some effects of temperature on carbon dioxide fixation by isolated chloroplasts
1.
1. Isolated pea chloroplasts were used to determine effects of temperature on photosynthetic CO2 fixation in saturating light and high CO2.
2.
2. Increases in temperature between 5° and 30° increased the maximum rate and shortened an initial induction period. The maximum rate was not an exponential function of temperature.
3.
3. Above 20°, values for the Q10 were less than 2. Below 15° they were greater than 2 and increased progressively, with decreasing temperature, to values as high as 9.
4.
4. The results, obtained with a purely photosynthetic system, support earlier work with intact organisms which led some investigators to conclude that photosynthesis did not obey the Arrhenius law. It is suggested that this may be a consequence of the cyclic nature of the reactions involved.
