Stages of photosynthesis (reactants, products, location, process, electron movement, phosphate movement, molec?

Photosynthesis occurs in two stages. The stages are known as the light reaction and dark reaction. Light- reactions take place in the presence of light. Dark reactions do not need direct light, but dark reactions in many plant occur throughout the day.

Light reactions occur mainly in the pile of tilakoid grana in chloroplasts. Here, the sunlight is converted into chemical energy (ADP → ATP) and (NADP → NADPH + H+). Chlorophyll absorbs light energy and energizes an electron that starts to move (oxygen is a leftover, as electrons are drawn from water to replace those of chlorophyll, water splits into H+ and O2) . This starts the chain step that results in the production of ATP, NADPH + H+.

Dark reactions occur in the stroma. Carbon dioxide is converted into sugar using ATP, NADPH + H+. This method is called carbon fixation and the calvin cycle. Every cyclus ONE carbondioxide is bound to a 3-carbon. Carbon dioxide combined with the use of 5-carbon sugars develop 6-carbon sugar. Glucose.
