1. Section 4-4 & 4-6 “Cellular Respiration / Fermentation”
Write everything that is BLACK

2. 4.4 KEY CONCEPT The overall process of cellular respiration converts sugar into ATP using oxygen

3. Cellular respiration makes ATP by breaking down sugars.
Cellular respiration is aerobic (requires oxygen)
It happens in the mitochondria
mitochondrion
animal cell

4. Glycolysis must take place first.
anaerobic process (does not require oxygen)
takes place in cytoplasm
splits glucose into two three-carbon molecules
produces two ATP molecules

5. Cellular respiration is like a mirror image of photosynthesis.
The Krebs cycle transfers energy to an electron transport chain.
takes place in mitochondrial matrix
breaks down three-carbon molecules from glycolysis
Krebs Cycle
6H O 2
6CO 6O
mitochondrion
matrix (area enclosed
by inner membrane)
inner membrane
ATP
energy
energy from glycolysis 1 4 3
and
makes a small amount of ATP
releases carbon dioxide
transfers energy-carrying molecules

6. energy from glycolysis
The electron transport chain produces a large amount of ATP.
takes place in inner membrane
energy transferred to electron transport chain
oxygen enters process
ATP produced
6H O 2
6CO 6O
mitochondrion
matrix (area enclosed
by inner membrane)
inner membrane
ATP
energy
energy from glycolysis 1 4 3
and
Electron Transport
water released as a waste product

7. The equation for cellular respiration: C6H12O6 + 6O2  6CO2 + 6H2O
The reactants in photosynthesis are the same as the products of cellular respiration.

8. 4.6 KEY CONCEPT Fermentation allows the production of a small amount of ATP without oxygen.

9. Fermentation allows glycolysis to continue making ATP when oxygen is unavailable.
Fermentation is an anaerobic process
occurs when oxygen is not available for cellular respiration
does not produce ATP

10. Lactic acid fermentation occurs in muscle cells
glycolysis splits glucose into two pyruvate molecules
pyruvate and NADH enter fermentation
energy from NADH converts pyruvate into lactic acid
NADH is changed back into NAD+

11. Alcoholic fermentation is similar to lactic acid fermentation
Fermentation is used in food production.
yogurt
cheese
bread
