ETC AND CHEMIOSMOSIS Flashcards
In order for the ETC to synthesize ATP what is used
Series of redox reactions
what are the redox reactions used for?
Oxidize NADH2 → NAD. Unloading the hydrogen from the pick-up truck
An electrochemical potential difference (like a rechargeable battery except with H+) is produced across the inner membrane of the mitochondria
e- used to operate tiny biological switches (proton pumps) allow H+ to follow from the matrix to intermembrane space
↑ [H+] in intermembrane space provides the potential to drive synthesis of ATP during chemiosmosis
This is where O2 is used. O2 is the stuff that removes e- from the ETC. When e-, O2 and H+ combine, water will form. O2 is known as the final e- acceptor
Oxidative phosphorylation.
How many ATPs are produced by one NADH2
3
How many protons are pumped into inter membrane space for NADH2
6
how many electrons pass the proton pumps for NADH2
2 electrons pass through 3 proton pumps
how many proton pumps are there
3
how many protons are pumped into the inter membrane space for FADH2
4
how many ATP will each FADH2 create
2 ATP
how many electrons pass across the proton pumps for FADH2
2 electrons pass through 2 proton pumps
how many net ATP are made through the entire thing?
36
how many atp are made in glycolysis
4 but net of 2
how many NADH2 are in glycolysis
2… 6ATP
how many atp are made in prep step
-2
how many NADH2 are in the Prep step
2… 6 ATP
How many ATP are made in the krebs cycle
2
How many NAHH2 are in the krebs cycle
6… 18ATP
How many FADH2 are in the krebs cycle
2… 4 atp
What is basic ATP made by
substrate level phosphorylation
what is atp made by NADH2 or FADH2 made by
oxidative phosphorylation
what is substrate level phosphorylation
when phosphate is transferred from a substrate to ADP to form ATP
what is oxidative phosphorylation
the formation of ATP as a result of the oxidation of NADH2 and FADH2
