WebAug 20, 2024 · Light is necessary for the light reactions of Photosynthesis. This is why no photosynthesis occurs at night because there is no light to initiate the electron transport … WebWhen a pigment absorbs a photon of light, it becomes excited, meaning that it has extra energy and is no longer in its normal, or ground, state. At a subatomic level, excitation is when an electron is bumped into a higher …

WebJan 3, 2024 · As we have seen, the light-dependent reactions of photosynthesis require light energy and water and generate O2, ATP and NADPH. In the light-independent (or ‘dark’) reactions, the ATP and NADPH will provide free energy and electrons (respectively) for carbon fixation (the reduction of CO2 to make carbohydrates).
