Metabolism stuff (ATP stuff) Flashcards
Oxidation is when electrons are?
Removed
Reduction is when electrons are?
Added
True or false: NAD is a coenzyme
TRUE
NAD can hold __ electrons(s) and ___ proton(s)
2 electrons
1 proton
What happens to NADH and FADH2 during oxidative phosphorylation?
They are oxidized and their electrons are transferred through the etc
NADH and FADH2 creates a gradient and uses ATP synthase to add phosphorus, ADP to ATP
What are the steps in carbohydrate catabolism?
Glycolysis
Krebs
Electron transport
What does glucose turn into during glycolysis?
2 molecules of pyruvate
Where does glycolysis occur?
In the cytoplasm of all cells
Is there oxygen involved in glycolysis?
NO
End product of glycolysis
2 ATP
2 NADH
2 pyruvate
Is glycolysis an anaerobic process?
YES
End product of transition step?
2 NADH
2 CO2
2 Acetyl CoA
End product of Krebs cycle?
6 NADH
2 FADH2
2 ATP
4 CO2
What happens in the transition step?
One carbon is removed from pyruvic acid
Carbon attaches to form acetate and then attaches with coenzyme A which makes acetly co a
What happens to acetylCoA in Krebs?
AcetlycoA gets broken down
Electron transport chain occurs in the __ in prokaryotes and in the __ in eukaryotes
Plasma membrane
Inner mitochondrial membrane
What are the 3 carrier molecules in the electron transport chain?
Flavoproteins
Cytochromes
Ubiquinones
Flavoprotein description
Contain flavin
Coenzyme derived from vitamin B2
Ubiquinoone description
Coenzyme Q
Small nonprotein carriers
Soluble in lipid membrane
Cytochrome description
protiens with an iron containing group
Cytochrome C oxidase
Last molecule of ETC to transfer electrons to O2
What is Chemiosmosis?
High concentration of H+ molecules accumulate and flows back in through atp synthase
Total amount of ATP made in Prokaryote Respiration? (aerobic)
38 ATP
How much ATP is made in ETC?
34
