Answer to Question #85246 in Other Biology for Rajendra
NADPH H+ is produced during the first phase of photosynthesis that is associated with light-mediated water splitting and release of electrons. During the process, four quanta of light split one water molecule releasing two electrons and two hydrogen ions that are used to produce one molecule of NADPH H+. As a result, the production of four molecules of NADPH H+ requires at least sixteen quanta of light.
Answer: 16 light quanta.
