41 light dependent reaction diagram
The light reaction of light dependent reaction occurs in the chloroplast of the mesophyll cells of the leaves. The chloroplasts are double-membraned cell organelles that are comprised of stacked disc-like structures known as thylakoids. The pigment, chlorophyll, which is required for the process is present on the membrane of these thylakoids and this is where the light reaction occurs. The light-dependent reactions of photosynthesis Pass the mouse pointer over this diagram for more information. The diagram above - based on the Z-scheme - suggests the amount of energy in each compound and also partly explains their location in the membranes as energy, electrons, and H+ are passed between them, rather like a pinball game. Light-dependent reactions are the energy conservation phase of photosynthesis. The ultimate aim of these reactions is to convert light energy from the sun into chemical energy that can be utilized to make glucose during dark reactions. The chemical energy is o...
