While viewing the Electron Transport Chain simulation in Labster, it showed how electrons from electron carriers are 'dropped off' at the beginning of the process.Why did it show two different pathways electrons can take during this simulation
Electrons can be either passed on to the electron transport chain by NADH⁺ at the first complex (NADH⁺-coenzyme Q oxidoreductase) or at the second complex(FADH⁺-coenzyme Q oxidoreductase). I think that's what you're referring to.
