Aerobic Cellular Respiration Review
“I can illustrate that during cellular respiration the bonds in food and oxygen molecules are broken, resulting in new
compounds and releasing energy to be used in biological reactions that may combine with other elements to form amino acids
and/or other large molecules.”
1. In which organelle does cellular respiration take place?
Glycolysis: cytoplasm
Krebs’ Cycle/ETS: Mitochondrion
2.
What are the overall products and reactants of aerobic cellular respiration (show the formula
below)?
C6H12O6 + 6 O2
3.
6 CO2 + 6 H2O + 36 ATP
Describe the process of glycolysis. Be sure to include what goes into glycolysis and what comes out.
1. Glucose enters the cell
2. 2 ATPs provide the energy needed to break glucose into 2 pyruvic acid molecules
3. 4 ATPs are made
4. 2 NADH are made
4.
Describe the Krebs cycle. Include what goes in and what comes out.
1. Pyruvic acid enters the mitochondrion
2. Oxygen enters the mitochondrion
3. Pyruvic acid is broken down, CO2 forms
4. CO2 leaves the mitochondrion and the cell
5. 2 ATP, 8 NADH, and 2 FADH2 are formed
5. Describe the electron transport chain (system). Include what goes in and what comes out.
1. O2 is used to facilitate electron transfer from NADH and FADH2
2. H2O leaves the mitochondrion and the cell
3. 32 ATPs are formed
6. Which process (es) in cellular respiration require oxygen?
Krebs’ Cycle and ETS
7. Which process(es) in cellular respiration do not require oxygen?
Glycolysis
8. A woman was submerged in cold water for an hour, without being able to breathe; yet when she was
rescued the paramedics were able to resuscitate her. Explain why this was possible using your
knowledge of cellular respiration. (Hint: your body is able to slow down cellular processes in extreme
cold)
-Cellular processes slow down, so less ATP is needed to maintain life.
-Glycolysis continued to supply small amounts of ATP (without using oxygen).
9. Compare and contrast photosynthesis and cellular respiration. Use a diagram to help in your
comparison.
