Cellular Respiration Review questions And
Answers
Give the chemical formula for respiration
C6H12O6+ 6 O2 --> 6 CO2 + 6 H2O + 36 ATP
Why is cellular respiration called an aerobic process?
Because the process requires oxygen.
Which gas is released in the process of cellular respiration?
Carbon Dioxide
How many total net ATP molecules are produced by the breakdown of 1 glucose
molecule in cellular respiration?
36
Name 3 stages of cellular respiration
Glycolysis, Krebs Cycle, and ETC(Electron Transfer Chain)
Where does Glycolysis take place?
the Cytoplasm
Where does the Krebs Cycle take place?
in the matrix of the mitochondria
Why is oxygen required for cell respiration?
to take away electrons after the ETC (combines with H+ to make water)
What molecule (substrate) does the process of glycolysis start with?
Glucose
If oxygen is present, what happens after glycolysis?
Krebs Cycle
What's the starting molecule for the Krebs Cycle?
Pyruvic Acid gets converted into acetyl CoA
What's the process that happens after the Krebs Cycle?
Electron Transport Chain {ETC}
Which molecules carry high energy electrons to the ETC?
NADH & FADH2
