What change occurs duringphotosynthesis?
In , the sun's solar energy is converted to chemical energy. The chemical energy is stored in the form of glucose (sugar). Carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water. Photosynthesis occurs in two stages. These stages are known as the light reaction stage and the dark reaction stage. The light reaction stage takes place in the presence of light and occurs within the chloroplast grana. The primary pigment used to convert light energy into chemical energy is chlorophyll a. Other pigments involved in light absorption include chlorophyll b, xanthophyll, and carotene. In the light reaction stage, sunlight is converted to chemical energy in the form of ATP (free energy containing molecule) and NADPH (high energy electron carrying molecule). Both ATP and NADPH are used in the dark reaction stage to produce sugar. The dark reaction stage is also known as the carbon fixation stage or the Calvin cycle. Dark reactions occur in the stroma. The stroma contains enzymes which facilitate a series of reactions that use ATP, NADPH, and carbon dioxide to produce sugar. The sugar can be stored in the form of starch, used during , or used in the production of cellulose.
How does chemiosmosis occur in photosynthesis
Respiration occurs in several different compartments of the cell: glycolysis occurs in
the cytosol, the link reaction occurs in the matrix of organelles called mitochondria.

photosynthesis, which does not ..
In plants and algae, photosynthesis takes place in organelles called chloroplasts. A typical plant cell contains about 10 to 100 chloroplasts. The chloroplast is enclosed by a membrane. This membrane is composed of a phospholipid inner membrane, a phospholipid outer membrane, and an intermembrane space between them. Within the membrane is an aqueous fluid called the stroma. The stroma contains stacks (grana) of thylakoids, which are the site of photosynthesis. The thylakoids are flattened disks, bounded by a membrane with a lumen or thylakoid space within it. The site of photosynthesis is the thylakoid membrane, which contains integral and peripheral membrane protein complexes, including the pigments that absorb light energy, which form the photosystems.

This occurs until a rate is reached where photosynthesis can't happen any faster; either due to a lack or carbon dioxide or water, or the temperature being too high/low, or having all enzymes functioning and no more to make it go faster!
