ATP synthase structure
What makes up the F0 unit? What makes up the F1 unit? |
F0
-proton channel -ring of 10-14 c---rotates -b stalk F1 -y stalk --rotates -alpha, beta ring |
|
|
How many ATPs made in one 360 rotation?
|
3
|
|
|
What are the two main carriers in the inner membrane of the mitochondria?
|
ATP/ADP translocator (ANT)
-ATP moves to intermembrane space -ADP moves to matrix Phosphate Carrier -phosphate moves into matrix -OH moves to intermembrane space |
|
|
How is ATP moved out of the matrix of the mitochondria?
|
The ATP/ADP translocase works with phosphate carrier at expense of 1 proton ( into matrix) to move ATP out.
|
|
|
What two things inhibit ANT (ATP/ADP Translocase)?
|
Bonkrekic Acid - inhibit on the matrix side
Atractyloside-- inhibit on the cystolic side |
|
|
What is the P/O ratio?
For cytoplasmic NADH by malate-asparate shuttle? For cytoplasmic NADH by glycerol 3 phosphate shuttle? NADH matrix? FADH2 matrix? |
The number of phosphate consumed per oxygen atom in ATP synthesis by mitochondria.
-equivalent to number of ATP made per oxidation of molecule 1. 2.5 2. 1.5 (remember how it uses FADH2 in the end) 3. 2.5 4. 1.5 |
|
|
What is total number of ATP made for complete oxidatio of glucose?
|
30 or 32
