Who wrote the music and lyrics for Kinky Boots? The high energy electron enters an electron transport chain. Thylakoids are disk-shaped structures that are stacked like pancakes within the chloroplast. In addition to light energy, the process also requires water and carbon dioxide. When pigments are extracted, the antenna complexes, reaction centers, and ETCs have been disassembled, so the energy is given off as fluorescence and/or heat. Life on earth is dependent on photosynthesis for what two things? Plants use sunlight to produce oxygen and store chemical energy in glucose as part of photosynthesis. Short answer: ATP synthesized by the light-dependent reactions are used only in light-independent reactions during the Calvin-Benson-Bassham cycle, energizing carbohydrate (glucose) synthesis. C.
