AIM: What is the difference between
aerobic and anaerobic cellular
respiration?
DN: Explain how plants regulate water
loss. Be sure to use the words
stomates and guard cells in your
explanation.
HW: page 238-239 # 14-16, 21, 22
What is the equation for
Cellular Respiration?
C6H12O6 + O2
CO2 + H2O + ATP
Releases CO2 by breaking down
glucose molecules in the presence of O2
Energy in organic food molecules
(glucose) is used to produce ATPenergy the body can use
It is an enzyme controlled reaction
Where does cellular Respiration
occur?
MITOCHONDRIA
Two types of cellular respiration
Aerobic and anaerobic
Oxygen
No oxygen
Aerobic Respiration
• Uses O2 and glucose
Raw materials= O2 and C6H12O6
End products= CO2, H2O and ATP
How do these material get into
and out of our cells?
O2 (oxygen):
breathe in, diffuses
into blood and
carried to cells
C6H12O6 (Glucose):
food we consume,
diffused into blood
and carried to cells
Do plants carry out aerobic
respiration?
YES!!!!
Why do ALL living things carry
out cellular respiration?
To carry out life processes: metabolism
Anaerobic Cellular Respiration
• Organisms make ATP
(energy) without
oxygen
• There are two types of
anaerobic respiration
– Alcoholic fermentation
– Lactic Acid
Fermentation
Alcoholic Fermentation
• Yeast and bacteria
Why does bread have so
many holes?
The gas that is released
during fermentation
creates bubbles and
pockets that make
bread rise
Lactic Acid Fermentation
• Bacteria and
animal muscle
cells when they
run out of O2
Alcoholic vs Lactic Acid
Fermentation
1. What is the organic compound used by
both?
2. What is their main product?
3. How are they different?
1. Alcoholic fermentation produces
2. Lactic Acid fermentation produces
4. What organisms utilize alcoholic
fermentation?
5. What organisms utilize lactic acid
fermentation?
