Photosynthesis is the process which takes place in the of leaves, and turns water and into and glucose through the absorption of light. The rate of photosynthesis is affected by many factors, such as , light intensity, water availability and the concentration of carbon dioxide.
During the light-dependent reaction, causes a pair of electrons to leave a molecule of and enter the electron transfer chain. The photolysis of produces oxygen, electrons and , the latter of which build up in the inner thylakoid space. They then diffuse back into the stroma through molecules, generating a molecule of ATP from ADP, and are accepted by an electron carrier to produce .
The light-independent reaction is otherwise known as . In it, carbon dioxide and RuBP react under the action of the enzyme to produce two molecules of . These are then reduced using a proton from reduced NADP and energy from the hydrolysis of ATP, which produces triose phosphate. Some triose phosphate is converted to useful organic substances, including starch, cellulose and lipids, but most is used to regenerate . Meanwhile, is cycled back into the light-dependent reaction.
