This is, by far, the best explanation of photosynthesis I've ever seen. I'm an idiot father trying to help my daughter understand this process for her 9th grade biology class. I wish they would use this technique in her school. If they did, she could teach me. Great job !

Ferredoxin receives high-energy electrons from photosystem I. While light is used to give energy to this high energy electron, the electron itself originally came from the water molecule that was split to provide electrons to photosystem II. I hope this helps :)

THANK YOU SO MUCH KEVIN 😄 This shows photosynthesis really well and made me understand how the electrons and H+ flow through the thylakoid membrane and i feel a bit better about the second midterm for BISC 101!

That clarification question by Erin (about the H ion vs H atom) and your explanation were SO helpful. I'm very rusty, and I couldn't even articulate my question, but that was it! This whole thing was awesome! Thank you both!

Good day, I'm back again haha, I would like to ask what happened to the other electron during the splitting of water? does it stays in the lumen or it was transferred also to the PS II together with the other electron? thank you.
@DrKevinLamSFU3 жыл бұрын
All of the electrons released from the water are fed into PSII :)

Its a great model for a first approach. I would like to create a smiliar model for my students. What material did you use to make the "electrons"?
@DrKevinLamSFU4 жыл бұрын
Thanks, Tobias :). The electrons were these plastic practice/wiffle golf balls I got from the dollar store. They come in white and bright yellow, but they ran out of yellow ones so my wife helped me paint them yellow. If you step on the seam gently, they split into two halves, so they won't roll around once you place them down. Please note that I made a bit of a mistake in making the hydrogen red and the oxygen white (when the convention is the other way around). Have fun! :)

What Materials Did You Use?
@DrKevinLamSFU8 жыл бұрын
+Elizabeth Reyes For the chloroplast model, I used paper towels for the membrane, poster paper for the enzymes and carriers, yellow plastic wiffle golf balls for the electrons (they split in half if you squeeze them along their seam in a nutcracker, so that they won't roll around), Tennis balls for the protons, and large styrofoam balls for the oxygen. for ATP, I bought a long 20-pack of sponges and picked out the blue ones for the adenosine , and I painted white styrofoam balls with yellow acrylic paint and connected them with bamboo skewers. All of this stuff is cheapest in dollar stores (even the paint and paintbrushes!)... styrofoam balls tend to be sold more often in the independent dollar stores than the chain ones (crafts stores have them too, but it's way more expensive). I made a mistake though: the hydrogens should be white and the oxygens should be red (if we're following conventional colours for these atoms), so if you can use a darker background for the model, it might be better to use the red tennis balls (or something bigger, if possible) as oxygen atoms, and white wiffle golf balls or styrofoam balls for hydrogens (you'll need a darker background for these "hydrogens" to show up more clearly, though).' I hope that helps! Have fun! :D
