Cellular Respiration Review


Notes

  • You may use your notes on the test.

  • Whether or not you use them you will turn them in with your test on Wed.


Cellular resp. releases energy by…

  • A. Breaking down food molecules

  • B. Breaking down ATP

  • C. Breaking down CO2

  • Answer is:

  • Food molecules are broken down to provide your cells with energy.


Know the 3 parts of Cellular Respiration(The precursor & its 2 stages)


The 3 parts are…

First comes…

Glycolysis

Second…

Krebs Cycle

Third…

Electron Transport Chain


Krebs Cycle

  • Starts with pyruvate

  • Produces NAD+

    (p. 210)


Know: e- transport chain

  • Occurs where?

  • Mitochondria, (in the inner membrane.)


Where does Glycolysis occur?

*In the Cytoplasm

What does it begin with?

*Glucose


Glycolysis produces how many ATPs? (net production)

2


Know the equation for cellular respiration.

C6H12O6 + 6O2 Energy + 6H2O + 6CO2

(Balanced)


Know that the electron carrier in cellular respiration is:


NAD+


What is the final product of lactic acid fermentation?


Lactic Acid


What kind of cells does Lactic Acid Fermentation mainly occur in?

Muscle cells


During Lactic Acid Ferm.

  • NAD+ is recycled so that ______GLYCOLYSIS____ can continue.

  • Hint: This produces 2 ATPs.


What are the final products of alcoholic fermentation?


CO2Ethanol

Used to make beer, wine, alcoholic beverages.


How many ATPs are formed from glycolysis + cellular respiration?


36 ATPs


In Cellular Respiration

  • 1 Molecule of glucose yields how many ATPs?

    36

    This is glycolysis + cellular resp.


If no oxygen is present the cell will go through…


FERMENTATION


*AEROBIC means:

Uses OXYGEN

*ANAEROBIC means:

Uses NO OXYGEN


Cellular Respiration uses

  • Oxygen

  • Cells that don’t use oxygen / don’t go through c.r. , are anaerobic bacteria

  • Can cause food poisoning
