Video Transcript

Okay, So this question wants to know what happens during the light dependent reaction. So in the light dependent reaction, H 20 is gonna enter plant cells. So then you have h 20 in your plant cells. That's actually going to use light energy to break that h 20 apart into separate parts, and electrons are going to be released from the H 20 molecule. These electrons are gonna get shot through the up to the top of the mile high liquid membrane using on transport proteins, and then they're actually gonna fall back down through the thigh liquid membrane, so they're gonna fall down through the sky liquid membrane. What happens? This is called an electron transfer chain. And what happens as the electron falls through that chain that's going to release energy, and that energy is going to be used to complete the light dependent reaction process. So what answer is going to be be, um, the electron they're gonna fall are flow through the electron transfer chain
