Cellular respitarion & fermentation Flashcards
Where does glycolysis occur?
cytoplasm
Where does the krebs cycle (citric acid cycle) occur?
mitochondrial matrix
Where is the electron transport chain located?
the inner membrane of the mitochondria
What is the chemical formula for cellular respiration?
C6 H12 O6 + 6O2 -> 6CO2 + 6H2O + ATP (energy)
Which step makes the most ATP?
Electron Transport Chain
What does the krebs cycle break down?
Acetyl CoA
What does the krebs cycle produce?
ATP, NADH, and FADH2 molecules.
In the krebs cycle, 1 glucose is completely broken down in 2 turns. What does it create?
6 NADH, 2 ATP, 2 FADH2, 4 CO2
What serves as the final electron acceptor in the etc?
Oxygen
What does glycolysis do?
Converts glucose into pyruvic acid
What does glycolysis produce?
Glycolysis produces ATP and NADH when glucose is converted into pyruvic acid
What are the electron acceptors?
NAD+ and FAD+
What are the electron carriers?
NADH and FADH2
What does anaerobic mean?
Requires no oxygen
What does aerobic mean?
Requires oxygen
What does glycolysis break down?
Breaks 1 glucose (6-carbon) molecule into 2 pyruvic acid (3-carbon) molecules.
How much atp is used in the process of glycolysis?
2
How many ATP does each cell produce per glucose?
It varies, but usually 36 ATP per glucose.
What happens during the krebs cycle?
Pyruvic acid is converted into CO2 and water in the presence of oxygen, producing a large amount of ATP.
