Photosynthesis - 76.Electron Transport System Molecules (Energy Transfer Molecules)Many chemical reactions of metabolism are oxidation-reductions that utilizea chain of electron transport molecules. Electron carriers, which are oftencoenzymes, make it possible for us to trap and use solar energy inphotosynthesis by utilizing oxidation-reduction reactions to pass electrons,controlling their energy. In the process of photosynthesis, the electrontransport carriers are embedded in the thylakoid membranes.The most important energy transfer molecule in photosynthesis is thecoenzyme, NADP+.Leaf Structure and PhotosynthesisWhen one examines a typical leaf, the relationship of its structure to its functionin photosynthesis becomes obvious. Water and carbon dioxide must be providedto the chloroplasts, and light must be available. Most leaves are flat providingmaximum surface area for sunlight. The leaf surface layer of cells is the
