During the stage of photosynthesis referred to as the light-dependent reaction, 12 molecules of water begin the process of reacting with six molecules of carbon dioxide to produce one molecule of glucose, six molecules of oxygen and six molecules of water.
Is the production of ATP in photosynthesis similar to the production of ATP in cellular respiration? Photosynthesis is often described as the reverse of cellular respiration. Respiration breaks down complex molecules to release energy that is used to make ATP. Photosynthesis takes energy from photons and uses it to build complex molecules. However both systems use an electron transport chain and associated proton pump and ATP synthase as a key part of the process.
