Oxidative Phosphorylation Flashcards
What is the cristae
The folded inner membrane of the mitochondria
Where does link and Krebs occur
in the mitochondrial matrix
What is opposite the matrix
The inter membrane space
How many protons can reduced NAD carry
1 proton
How many protons can reduced FAD carry
2 protons
What does reduced NAD/FAD release?
Protons and electrons.
What do electrons enter released from reduced FAD and NAD
Electrons enter the electron carrier chain and travels along the electron carrier proteins. These electrons have high energy
What benefits does having high energy in electrons have
When they enter the ledge on carriers, electrons slowly release energy that gets used to pump protons across the cristae into the inter membrane space via active transport
What happens as a result of this pumping protons in the inter membrane space
The proton concentration increases. This generates a proton concentration gradient as hella in IM space and less in matrix. So diffusions happens naturally through the enzyme ATP synthase via chemiosmosis down the electrochemical gradient
How does ATP get made via ATP synthase
ATP synthase requires protons to help it turning the enzyme, bringing ADP and Pi closer together making ATP
We have protons and electrons left so what happens to them???????
Oxygen is the final terminal electron acceptor - binding with the protons and electrons to make water as the final product
