Factors affecting oxidative phosphorylation by subcellular particles isolated from cotton seedling hypocotyls

Factors affecting oxidative phosphorylation by subcellular particles isolated from cotton seedling hypocotyls.

Properly prepared mitochondrial fractions from plant sources are capable of incorporating inorganic phosphate into high energy bonds upon the oxidation of members of the tricarboxylic acid cycle (3, 6, 7). Oxidative phosphorylation has been demonstrated in preparations from a wide variety of plant sources. This author reported that a high concentration of BSA3 in the grinding medium was necessa...

Oxidative and phosphorylative activities of mitochondria isolated from cotton hypocotyls.

Mitochondria isolated from 2 strains of cotton plant hypocotyls (Gossypium hirsutum L. var. Rex smooth leaf and Rex glandless) were examined for their oxidative phosphorylation activities. Bovine serum albumin at a relatively high concentration was essential in the extraction medium for the isolation of oxidatively active mitochondria from both strains of cotton. Phosphorylation was obtained on...

Oxidative phosphorylation catalyzed by cytoplasmic particles isolated from malignant tissues.

Oxidative Phosphorylation and Glycolate Oxidation by Particles from Spinach Leaves.

It has recently been reported (2) that oxidative phosphorylation occurs when organic acids of the citric acid cycle are supplied as substrates to particles isolated from the cotyledons of etiolated lupine seedlings. The ratios of the number of moles of orthophosphate consumed to the number of atoms of oxygen taken up (P/0 ratios) were found to be as high as those previously reported only for an...

Photosynthetic phosphorylation catalyzed by factors isolated from photosynthetic organisms.

where DaUk converges strongly to Dau in L2(Q). Furthermore, daf(uk)Dv converges strongly to da,,(u)Dv in L2(Q) by dominated convergence. Hence, each term in the sum for a (u k, V) converges to the corresponding term in the sum for a(u, v), (G(uk), v)m . (G(u), v)m for each v in V, and the proof of Lemma 3 is complete. Proof of Theorem 1: By Lemma 2, it suffices to show that the mapping G is one...
