The Light Reactions of Photosynthesis. Light is absorbed and the energy is used to drive electrons from water to generate NADPH and to drive protons across a membrane. These protons return through ATP synthase to make ATP.on:
Four ATP molecules are produced during the Krebs cycle. The final step of cellular respiration is the electron transport chain.
Chloroplast has evolved from photosynthetic bacteria
