Abstract
The respiration of cotyledons from light-grown soybean seedlings (Glycine max L., Amsoy) showed a sharp peak of activity after two weeks of growth, followed by a slighter increase during senescence. Cotyledon respiration was found to be strongly cyanide-resistant. Mitochondria isolated from cotyledons at various stages of development displayed a progressive improvement in structure. The rate of succinate oxidation closely paralleled that of respiration, being also highly cyanide-resistant. Cotyledon mitochondria also oxidized glycine. However this oxidation was remarkably cyanide- and antimycin-resistant.
