The right answers are A, B and D
The emission of a molecule of O2 requires the oxidation of 2 molecules of H2O; there are 4 electrons transferred.
2 H2O ----> O2 + 4 H + + 4 e-.
In photosynthesis, it is not an ADP synthase but an ATP synthase. It is an enzymatic protein complex found in the mitochondrial ridges, the thylakoid membrane, and the plasma membrane of bacteria and archaea. The role of this membrane protein is to synthesize adenosine triphosphate (ATP) from the proton electrochemical gradient maintained by the respiratory chain and adenosine diphosphate (ADP).
Photosynthesis comprises two sets of distinct reactions:
* Reactions directly dependent on light, called "light phase" or "light phase".
* Reactions not directly dependent on light, called "dark phase", "dark phase" or "biochemical phase".
