When NADH, ADP and Pi are supplied, these vesicles synthesize ATP. How will the rate of synthesis be affected if the pH of the suspension buffer is raised?
In the formation of ATP from ADP, NADH becomes NAD+, by the following reaction.
NADH -----> NAD+ + H+ + 2e-
Therefore, increasing pH of the suspension, that is, decreasing the [H+], promotes the oxidation of NADH and hence an increase in the rate of synthesis of ATP may be observed.

ATP + H2O <---> ADP + Pi Calculate the ΔG for ATP hydrolysis when the concentrations of ATP, ADP, and Pi are all 1M R = 1.98 x 10-3 T = 310 kelvin ΔGº = -30.5 kJ/mol
The reaction for the hydrolysis of ATP is: ATP rightarrow ADP + Pi + 7.3kcal Is this an endergonic or exergonic reaction and why? Draw a reaction energy diagram for this reaction (do not need to include specific numbers) and label: X and Y axis, reactants, products, transition state, energy of activation. Draw an additional curve on your diagram above (use a dotted line or another color to distinguish) to indicate how the progress of reaction would be affected by...
Consider the hydrolysis of ATP: ATP(aq) + H2O(l) → ADP(aq) + Pi(aq). This reaction has ΔH°= −24.3 kJ/mol and ΔS°= +21.6 J/mol-K.

Discuss ATP synthesis and ATP hydrolysis; How do cells obtain the energy to synthesize ATP? Why do cells hydrolyze ATP? What do cells do with released energy obtained from the hydrolysis of ATP?
Investigators introduce two proteins into the membrane of artificial lipid vesicles: (1) an ATP synthase isolated from the mitochondria of cow heart muscle, and (2) a light-activated proton pump purified from the prokaryote Halobacterium halobium. The proteins are oriented as shown in the diagram. When ADP and P; are added to the external medium and the vesicle is exposed to light, would this system produce ATP? H LIGHT protein pump ATP synthase Choose one: O No, because no electron-transport chain...
