Cellular Respiration (unit C) Flashcards
What are the two types of cellular respiration?
Aerobic cellular respiration and anaerobic cellular respiration.
What is the major difference between the two types of cellular respiration?
One takes place without o2 and one takes place with o2
What is the overall equation for aerobic cellular respiration?
C6 H12 O6 + 6O2 = 6CO2 + 6H2O + ATP
Which reactant in cellular respiration is oxidized? What does it become?
Glucose. It becomes CO2, Water, ATP
Which reactant in cellular respiration is reduced? What does it become?
Oxygen. It becomes 6 Carbon, 6 water, ATP
Where does glycolysis appear?
Cytoplasm of the cell.
What are the inputs of glycolysis? Outputs? Be sure to include numbers of each.
Inputs of glycolysis are 1 glucose, 2 ATP and 2 NAD+ molecules and the outputs are 2 pyruvate molecules, 4 ATP and 2 NADH.
Where does glycolysis occur?
The cytoplasm of the cell.
Why is glycolysis considered an anaerobic process?
Because it doesn’t require O2.
Why do we say that glycolysis has a “net gain of 2 ATP” when it produces 4 ATP?
Because 2 ATP molecules are used in the first half of glycolysis.
What are the inputs of pyruvate oxidization? Outputs? We should include the numbers of each.
2 pyruvate, 2 NAD+, 2 CoA = 2 Acetyl-CoA, 2 NADH, 2 CO2
Where does pyruvate oxidation occur?
Mitochondrial matrix
Why is CO2 produced during pyruvate oxidization?
To make Acetyl-CoA
What are the inputs for krebs cycle? Outputs? Be sure to include numbers of each.
2 Acetyl-CoA, 2 ADP, 6NAD+, 2 FAD
4 CO2, 2 ATP, 6 NADH, 2 FADH2
Where does Krebs cycle occur?
Mitochondria
