What delivers high-energy electrons to the ETC
NADH and FADH2
Why are the e- carried to the ETC
To create ATP vis chemiosmosis
How do the electrons move
They move in steps from carrier to carrier as they move closer to oxygen
What happens to each carrier molecule while moving down the chain
They increase slightly in electronegativity
What is oxygen’s role
It’s the ultimate e- acceptor at the end of the chain and is the most electronegative
Inputs
10 NADH (2 from glycolysis, 2 from the pyruvate, and 6 from Krebs cycle)
2 FADH2 (from the 2 turns of the Krebs cycle)
6 O2
Outputs
30-32 ATP
12 H2O
