Electron Transport Chain Explained (Complex 1-4, Q Cycle, Reduction Potential) | Clip

Welcome to Science With Tal! In this video, we will cover how the electron transport chain functions by analyzing complex 1 to 4 and all the components in between that make it happen (cytochrome molecules, NADH, FADH2, CoQ-CoQH2, FMN, etc.). We will also discuss some more general topics such as the reduction potential that are super important to understand how the ETC operates.
