Isolation and Oxidative Properties of Intact Mitochondria from the Leaves of Sedum praealtum: A Crassulacean Acid Metabolism Plant 1

AUTOR(ES)
RESUMO

A procedure is described for preparing intact mitochondria from leaves of Sedum praealtum D.C., a plant showing Crassulacean acid metabolism. These mitochondria oxidized malate, pyruvate, α-ketoglutarate, succinate, NADH, NADPH, and isocitrate with good respiratory control and ADP/O ratios better than those observed in mitochondria from other photosynthetic tissues.
