How linear electron flow in the light reactions results in the formation of ATP, NADPH, and O 2. How is ADP converted to ATP? The four photosystems absorb light energy through pigments—primarily the chlorophylls, which are responsible for the green color of leaves.The light-dependent reactions begin in photosystem II. 4. Each … The excited electrons then travel down a short electron transport chain, and while doing so they pump H+ molecules (hydrogen molecules) into the inner thylakoid space across the thylakoid membrane from the stroma. The next required reactant is carbon dioxide. This process converts light energy to chemical energy, which is stored in the sugars. Consequently, … The cells found in both plants and animals need to produce energy. This process is important for two reasons. High-light illumination of photosynthetic organisms stimulates the production of singlet oxygen by photosystem II (PSII) and causes photo-oxidative stress.
