2
New cards
Where is the mitochondrial ETC located?
Inner mitochondrial membrane.
3
New cards
What does NADH donate to the ETC?
High-energy electrons.
4
New cards
What does FADH2 donate to the ETC?
High-energy electrons.
5
New cards
What is the first major ETC complex for NADH electrons?
NADH dehydrogenase complex.
6
New cards
What mobile carrier moves electrons between ETC complexes?
Ubiquinone, also called Q.
7
New cards
What other mobile electron carrier is used in the ETC?
Cytochrome c.
8
New cards
What is the final ETC complex before oxygen?
Cytochrome c oxidase complex.
9
New cards
What is the final electron acceptor in the ETC?
Oxygen.
10
New cards
What happens when oxygen accepts electrons and H+?
Water is formed.
11
New cards
Which ETC complexes pump protons according to the lecture?
NADH dehydrogenase, cytochrome c reductase, cytochrome c oxidase.
12
New cards
Where are H+ pumped during mitochondrial electron transport?
Into the intermembrane space.
13
New cards
What happens to electrons as they move through the ETC?
They lose energy.
14
New cards
What is the energy lost by electrons used for?
Pumping H+ across the inner mitochondrial membrane.
15
New cards
Why does NADH produce more ATP than FADH2?
FADH2 skips the first proton pump.
16
New cards
Where does FADH2 enter the ETC?
At succinate dehydrogenase, then ubiquinone.
17
New cards
What is the easiest ETC memory trick?
Electrons go down the chain; protons get pumped up.
