Metabolism 3 Key Concepts Flashcards
What do the NADH and FADH2 molecules formed during aerobic respiration each contain?
high energy electrons
Where do NADH molecules carry electrons to?
Inner mitochondrial membrane
What occurs to electrons at the inner mitochondrial membrane?
They are transferred to a series of membrane-associated proteins (the electron transport chain)
What does the electron transport chain produce?
A proton (H+) gradient, which forms as electrons move through electron carriers
What does chemiosmosis utilise the electrochemical gradient to do?
Produce ATP
When does anaerobic respiration occur?
When oxygen is not available
What does anaerobic respiration involve?
The fermentation of NAD+
What are recycled NAD+ and NADH able to do?
Enter glycolysis and contribute to ATP production.
