Role of adenine nucleotides, adenosine, and inorganic phosphate in the regulation of skeletal muscle blood flow.
Experiments were performed on isolated frog sartorius muscle and in situ dog skeletal muscle to determine whether adenine nucleotides and their degradation products are released during contraction in concentrations capable of producing arteriolar dilation. ATP was not detectable ( < 1 O 8 M ) in the bathing solution of the resting or contracting frog sartorius muscle. Inorganic phosphate (P,) i...
متن کاملAdenosine Receptor by Adenine Nucleotides
Adenosine and adenine nucleotides shorten the action potential duration of atrial myocytes and activate a specific acetylcholine and adenosine receptor-operated potassium outward current referred to as IKACh,Ado The objective of this study was to determine whether adenine nucleotides shorten the action potential duration and increase IKAChAdo in guinea pig atrial myocytes by directly activating...
متن کاملUptake of Adenine Nucleotides by Respiring Mitochondria during Active Accumulation of Ca++ and Phosphate.
The large scale, respiration-linked accumulation of Ca+f ions by isolated mitochondria (l-lo), which leads to deposition of amorphous granules of calcium phosphate (5, 7, 8, lo-12), has been found to be accompanied by accumulation of significant amounts of a phosphate derivative (or derivatives) hydrolyzed to inorganic phosphate by boiling in 1 N HCl for 7 minutes (5). In this paper it is demon...
متن کاملBinding of adenine nucleotides to mitochondrial membrane.
It has been reported from different laboratories [l-4] that mitochondria are capable of binding ATP. However the exact magnitude of binding, and the relevance of this process to the mechanism of oxidative phosphorylation are still unknown, due to the extremely low amounts of bound nucleotides, and to some difficulties in carrying out the measurements. The key to clarification of this problem ha...
متن کاملEffects of adenine nucleotides on hydrogen-ion transport in chloroplasts.
1-10 muM ATP stimulated H(+) uptake and slowed the release of H(+) in the dark in chloroplasts illuminated at pH values at which photophosphorylation can occur, but not at pH 6.5. This ATP stimulation of H(+) uptake was abolished by an antiserum to the chloroplast coupling factor and was reduced by the energy transfer inhibitors phlorizin and Dio-9. ATP synthesis after illumination was also enh...
