ATP and NADP+ During what stage of photosynthesis are ATP and NADPH converted to ADP + Pi and NADP+? a. the light-dependent reactions b. the light-independent reactions c. both of the above d. none of the above Energy for the Calvin cycle is supplied by from the light reactions. a. ...
Is ATP synthase a passive facilitated diffusion or an active transport? What type of molecule is ATP? Describe ATP synthase with regard to: a) its molecular structure, b) its cell location and function, and c) its specific activity in coupling electron transport to ATP production. About ATP ...
In ATP synthase, X-ray structures, demonstration of ATP-driven gamma-subunit rotation, and tryptophan fluorescence techniques to determine catalytic site occupancy and nucleotide binding affinities have resulted in pronounced progress in understanding ATP hydrolysis, for which a mechanism is presented here...
ATPase activity generally refers to the breakdown of ATP, releasing energy for cellular processes, whereas ATP Synthase activity is synonymous with energy storage, capturing energy in the form of ATP. The direction of the reaction—synthesis or hydrolysis—depends on the specific enzyme and the cellu...

Myosin is known to be the smallest of molecular motors, yet it is essential to muscle contractions, and a form of ATP called ATP synthase is also a molecular motor used to build up adenosine diphosphate (ADP) for energy storage as ATP. Perhaps the most remarkable natural molecular motor disc...
