Where do the electrons come from?
10 NADH, 2 FADH₂
Where do the electrons go?
What does O₂ become after it gets an electron?
What is the immediate effect of the ETC?
It creates a hydrogen concentration gradient.
Where is a low hydrogen (H+) concentration created?
Where is a high hydrogen (H+) concentration created?
intermembrane space (of mitochondria)
What is the eventual effect of the ETC?
Where is the ETC located?
Inner membrane of mitochondria
