Title
Effect ofAntimycin A on Photosynthesis ofIntact Spinach Cbloroplasts
Marie‐Louise Champigny 1971
Other claims from this paper (9)
- Intervention effect Antimycin A increased carbon dioxide fixation rate in intact spinach chloroplasts.
- Intervention effect Antimycin A increased oxygen evolution rate in intact spinach chloroplasts.
- Association The stimulation was highest at saturating light intensity.
- Association Stimulation was independent of bicarbonate concentration.
- Intervention effect Antimycin A enhanced glycerate 3-phosphate synthesis.
- Intervention effect Antimycin A decreased dihydroxyacetone phosphate.
- Intervention effect Antimycin A decreased the chloroplast Michaelis constant for bicarbonate.
- Intervention effect Antimycin A did not decrease the Michaelis constant of ribulose 1,5-diphosphate carboxylase for bicarbonate.
- Mechanism The authors suggested antimycin A acts on the chloroplast outer envelope mechanism controlling carbon fixation.
