The energy is "stored" in every bond. The primary bonds that break are either the first and second phosphate or the second and third phosphate creating AMP or ADP. The middle letter stands for Mono, Di or Tri (meaning 1, 2 or 3 phosphates).


These chemo-synthetic bacteria gets energy from oxidation of inorganic compounds. Following table from Biology of Prokaryotes shows main reactions used by different species, This oxidation happens only if electron acceptor is available. These all reactions have negative Gibbs Free Energy, hence they are favorable reactions and happens spontaneously. ...


I only found a hint that this might be the case in this publication by Singh et al., stating Porphyrins, chlorins, bacteriochlorins, and isobacteriochlorins each have unique photophysical properties that are exploited by nature and can be used for diverse applications (1, 2). I don't have access to "The Porphyrin Handbook" (The first citation in the ...


I read on Wikipedia that basically 3 O2's (sorry for the lack of subscripts) come from water in the light reaction, and during the Calvin cycle H2O is produced from H+ ions and CO2 to make more H2O, which produces more O2 in the light reaction. Basically, 3 O2's come from the water and the other 3 O2's come from CO2-made H2O.


Equation you have mentioned is balanced chemical equation. In reality these are series of Redox reactions, major two as follows, Oxidation of oxygen from water in presence of light (energy from photon), $ 2H_2O \xrightarrow{Photons} O_2 + 4H^*$ Ions produced from above reaction reduces carbon dioxide , $4H^* + CO_2 \rightarrow (CH_2O) + H_2O$ So ...
