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.
Photosynthesis is the plant process where light energy is used to generate the production of ATP. The ATP so formed is used to form the bonds between carbon dioxide molecules and hydrogen atoms released from water by the light energy. The process forms sugar (glucose) molecules and produces oxygen as a waste product. At a glance, the equations: sugar + oxygen --> carbon dioxide + water + ATP energy (cellular respiration) and carbon dioxide + water + sun's energy --> sugar + oxygen (photosynthesis) look to be the reverse of each other.
