What turns sunlight into chemical energy?

Support the channel by joining our newsletter: https://bit.ly/watchclockwork So, we know that plants use sunlight to make food. That’s kind of one of the most important facts in our ecosystem. Plants and photosynthetic bacteria form the bedrock of our food chain and are one of the most important forces making Earth a habitable planet. But--how do we transition from solar energy to chemical energy? How exactly do plants store sunlight once it’s been captured? This requires one of the most important journeys on earth. In this video, we’ll take a trip down the electron transport chain in chloroplasts and see how cytochrome bf, plastocyanin, photosystem I, and ferredoxin work together to create the power necessary to make food from sunlight.

Find out in part 2 of our 4-part series on photosynthesis. We're going to explore how Photosystem 2, Cytochrome Bf, plastoquinone, photosystem 1, and ferredoxin work together to move electrons. We'll see how we can use those electrons as bait to bring more protons across the thylakoid membrane and into the lumen. From there, we'll see how Photosystem 1 excites electrons and helps them complete their journey by making NADPH. All this motion takes the energy of sunlight and helps convert it into chemical energy.
