2.2 Flashcards
Glycolysis is controlled by
Enzymes
Where does Glycolysis happen in
Cytoplasm
How many atp is produced in phase off stage
4
How many atp are used in the investment stage
2
Total net gain of atp is
2 atp
What enzyme releases of hydrogen
Dehydrogenase
How is hydrogen carried away from the Adp
Carried away by coenzyme NAD to make NADH with electrons
What is phosphorylation?
Enzyme controlled process, when phosphate is added to a molecule. ATP to ADP + Pi
Pyruvate breaks down into
A acetyl group and carbon dioxide and Hydrogen plus electrons
To form Acetyl CoA
Where does the pyruvate enter into the mitochondria ?
Into the matrix
Where does the citric acid cycle take place
In the matrix of the mitochondria
How do you make citrate?
Acetyl Group (2C) + Oxaloacetate (4C) = citrate (6C)
Citrate gradually changes back into…
Oxaloacetate
What is generated throughout the citric acid cycle?
ATP
What is released throughout the citric acid cycle?
Carbon dioxide and hydrogen plus electrons at each stage
How is hydrogen released?
Coenzyme NAD picks up hydrogen ions and electrons released by a dehydrogenase enzyme to produce NADH
Where does the electron transport chain occur?
Inner membrane in the mitochondria
What is used to release electrons and Hydrogen
NADH
What do electrons excite?
Carrier Proteins
What does the energy pump?
Hydrogen ions from the matrix to the inner membrane space
Name the enzyme that transports Hydrogen ions from the inner membrane space to the matrix.
ATP synthase
Explain ATP synthesis
Produces ATP from ADP + Pi as H+ ions return to the matrix through the ATP synthase
What combines with electrons in the end of the chain?
Oxygen
The oxygen molecule will also combine with…
2 hydrogen ions to make water
