KA7 Flashcards
Name of stage 1 cellular respiration?
Glycolysis
Name 2 phases of glycolysis?
Energy investment & energy pay-off.
Describe the energy investment phase of glycolysis?
When 2 ATP are required for phosphorylation of intermediates. ( ATP ARE USED UP.)
Describe the energy pay-off phase of glycolysis?
Produces 4 ATP 2 in 2 out.
What’s the net gain from glycolysis
2 atp
What enzyme removes hydrogen ions and electrons during glycolysis & citric acid cycle?
Dehydrogenase ( passes hydrogen To the NAD coenzyme which becomes NADH.
What’s the name of the co-enzyme molecule that the hydrogen ions and electrons are passed onto?
NAD
Does glycolysis require oxygen?
No
Where does glycolysis occur?
Cytoplasm.
Where does the citric acid cycle take place?
Matrix of the mitochondrion.
What is citrate formed from?
Acetyl group + oxaloacetate.
Where does NAD pass the hydrogen ions and electrons to?
Christae (inner membrane) of the mitochondrion to stage 3.
Besides hydrogen, what other substances are formed during the citric acid cycle?
Carbon dioxide + ATP.
What is the electron transport chain?
Series of proteins attached to the inner membrane of mitochondrion.
(Lil bobbles)
Where is the ETC found
Innner membrane
