7.4 Cellular Respiration Flashcards
What is the first stage of cellular respiration?
Glycolysis
What is the second stage of cellular respiration?
The Link Reaction
What is the third stage of cellular respiration?
The Krebs Cycle
What is the fourth stage of cellular respiration?
The Electron Transport Chain
What is the equation of glycolysis?
2 ATP + 2NAD+ + 2 Glucose –> 4 ATP + 2NADH + 2 pyruvate
Where does glycolysis take place?
In the cytoplasm
What is the equation of the link reaction?
2 pyruvate + 2 CoA + 2 NAD+ –> 2 Acetyl-CoA + 2 carbon dioxide + 2 NADH
Where does the link reaction take place?
In the mitochondria
What is the equation of the krebs cycle?
2 Acetyle-CoA + 6 NAD+ + 2 ADP + 2 FAD –> 4 Carbon dioxide + 6 NADH + 2ATP + 2 FADH2
Where does the Krebs cycle take place?
In the mitochondria
What is the equation of the electron transport chain?
6NADH + 2 FADH2 + O2 + ADP –> 30 ATP + H2O
Where does the electron transport chain take place?
In the mitochondria
What is the overall equation of cellular respiration?
C6H12O2 + 6O2 –> 6CO2 + 6H2O + ATP
What processes happen when there is oxygen present?
Glycolysis, the link reaction, and the electron transport chain.
How much ATP is made when there is oxygen present?
34 ATP
What processes happen when there is not oxygen present?
Glycolysis and fermentation
How much ATP is made when there is not oxygen present?
2 ATP
