  1. What are the three stages of cellular respiration?
    Glycolsis: Kreb's Cycle: ETC
  2. What happens if oxygen is not present. ( In Cellular Respiration)
    Fermentation
  3. Where does glycolysis take place?
    Cytoplasm
  4. What is the final product of glycolysis?
    (Glucose-_________)
    2 pyruvates
  5. Where does the Kreb cycle take place?
    mitochondria
  6. How do electrons become excited in the ETC
    They abosorb light energy from the sun
  7. what compound is made when hydrogens combine with oxygen in the ETC?
    H2O
  8. What is the chemical reaction for CR?
    C6+H12+O6+6O2=6CO2+6H2O+energy
  9. Where does Fermentation take place?
    cytoplasm
  10. What are the final products of latic acid fermentation? Alcohol fermentation?
    • Latic- pyruvic acid + NADH -> Latic Acid
    • Alcohol- pryuvic acid + NADH -> alcohol +CO2+NAD+
  11. What is the total number of energy molecules in glycolysis? and What are they?

  12. What is the net total of energy molecules made in glycolysis?
    2
  13. Explain the process of the Kreb's Cylce?and during step 3 what are the three molecules produced?
    breaks down one pyruvate (which was made into Acetyl- CoA) and ATP, NADH, CO2
  14. how many total ATPs are made from CR?
    36
