Photosynthesis - an overview | ScienceDirect Topics
Although light energy is frequently written as a in the overall reaction for photosynthesis, energy is not an actual reactant molecule. Light energy is written on the reactant side to indicate that this energy is needed for photosynthesis to proceed. Energy-wise, the overall reaction of photosynthesis is because the reactants contain less potential energy than the .

The net chemical reaction of photosynthesis captures sunlight energy to carbon dioxide by adding electrons and hydrogen to form glucose. Because electrons are added to the carbon molecules, new electrons are taken from water to replenish the system. Therefore, water is , producing oxygen gas. To balance this chemical equation, six molecules of carbon dioxide (CO2) are reduced to produce one molecule of glucose (C6H12O6).

Inside each chloroplast, the thylakoid membrane is extensively folded into a series of flattened sacs called . Because the thylakoid membrane is continuous, the thylakoid sacs are layered into rows and rows of stacks. Each stack is a (pl. grana). Inside each thylakoid is a fluid-filled area called the or . Surrounding the grana is the , a semi-fluid medium between the second and third membranes. Thylakoid membranes are packed with chlorophyll a and accessory pigments that absorb light energy to initiate photosynthesis. Extensive membrane folding and structure provides plenty of membrane space for pigment molecules to interact and absorb light energy.
