ATP and ETS- Bikman Flashcards
What is beta oxidation?
It is breaking down fatty acid chains into acetyl-CoA, FADH2, and NADH for every two carbons
What are the irreversible enzymes of the Kreb cycle?
citrate synthetase, isocitrate dehydrogenase, alpha ketogluterate dehydrogenase
What enzymes in the Kreb cycle are inhibited by NADH, ATP, or GTP?
isocitrate dehydrogenase and alpha ketogluterate
What steps in the Kreb cycle make CO2 and NADH?
isocitrate dehydrogenase and alpha ketogluterate
What steps in the Kreb cycle make FADH2?
succinate synthetase
What steps in the Kreb cycle make only NADH?
malate dehydrogenase
What steps in the Kreb cycle make ATP?
succinyl-coA synthetase
What other derivatives can enter the Kreb cycle?
ketones, amino acids, fatty acids, glucose
What are the products of one cycle of the Krebs cycle?
3 NADH, 1 FADH2, and 1 ATP
Where does the Krebs cycle take place?
In the mitochondrial matrix
Where does ETS take place?
In the mitochondrial inner membrane
How many H+ does ATP synthase need to make one ATP?
4 H+
How many H+ does NADH allow into the intermembrane space during ETS? How many ATP does this make?
10 H+; 2.5 ATP
How many H+ does FADH2 allow into the intermembrane space during ETS? How many ATP does this make?
6 H+; 1.5 ATP
What does ANT and VDAC do in the ETS?
It transfers ATP and ADP from the cytosol into the mitochondrial matrix
