Photosynthesis - 7 6 . Electron Transport System Molecules (Energy Transfer Molecules) Many chemical reactions of metabolism are oxidation-reductions that utilize a chain of electron transport molecules. Electron carriers, which are often coenzymes, make it possible for us to trap and use solar energy in photosynthesis by utilizing oxidation-reduction reactions to pass electrons, controlling their energy. In the process of photosynthesis, the electron transport carriers are embedded in the thylakoid membranes. The most important energy transfer molecule in photosynthesis is the coenzyme, NADP + . Leaf Structure and Photosynthesis When one examines a typical leaf, the relationship of its structure to its function in photosynthesis becomes obvious. Water and carbon dioxide must be provided to the chloroplasts, and light must be available. Most leaves are flat providing maximum surface area for sunlight. The leaf surface layer of cells is the epidermis, typically with a waxy cuticle layer that helps reduce water loss from
