Hydrolysis of ATP releases energy, which is used to drive both endergonic (requires energy) and exergonic reactions (releases energy but requires... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a ...
Free energy of ATP- hydrolysis fails to affect ATP-dependent potassium channels in isolated mouse ventricular cells. J. Mol. Cell. Cardiol. 22:183-190.Albitz, R., Kammermeier, H., Nilius, B. 1990. Free energy of ATP-hydrolysis fails to affect ATP-dependent potassium channels in isolated ...
The initial step in hydrolysis is the activation of the molecule to be hydrolyzed. This often involves the transfer of a phosphate group from adenosine triphosphate (ATP) to the molecule of interest. The addition of the phosphate group provides the necessary energy to drive the subsequent hydrolysi...
The H+/ATP ratio is an important parameter for the energy balance of all cells and for the coupling mechanism between proton transport and ATP synthesis. A... S Steigmiller,P Turina,P Graber - 《Proceedings of the National Academy of Sciences of the United States of America》 被引量: 173...
To further address the contribution of the N-terminal domains to the ATPase activity, we used an Hsp90 point mutant that is unable to bind ATP. Since heterodimers between the WT protein and this mutant showed WT ATPase activity, this mutant, although unable to bind ATP, still has the ...

(1) Does the magnitude(大小) of the free energy change for ATP hydrolysis increase or decrease as the pH increases from 5 to 6? Why? (6分)(2) A certain metabolic pathway can be diagramed asWhere A, B, C, and D are the intermediates(中间体), and X, Y, and Z are the enzymes...
ATP synthases of the F0F1 type are multi-subunit protein complexes anchored to membranes that convert proton (or sodium ion) gradients into chemical energy in the form of ATP.1 Proton gradients are established by divergent processes, such as respiratory electron transport in mitochondria or photosynt...
as separate subunits, up to four, or can be fused together as a single multidomain polypeptide (2); two hydrophobic membrane-spanning domains confer substrate specificity and two nucleotide-binding domains (NBD) provide, by hydrolyzing ATP, the chemical energy required to energize the transporter....
