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
