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 moleculesB. Breaking down ATPC. 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 CycleStarts with pyruvate

Produces NAD+(p. 210)

Know: e- transport chain

Occurs where?

Mitochondria, (in the inner membrane.)

*In the Cytoplasm

What does it begin with?*Glucose

Where does Glycolysis occur?

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?

CO2

EthanolUsed 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?

36This 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
