LO: SWBAB describe the difference
between aerobic and anaerobic cellular
respiration.
DN: Explain how plants regulate water
loss
HW: page 238-239 # 14-16, 21, 22
Cellular Respiration
C6H12O6 + O2
CO2 + H2O + ATP
Releases CO2 by breaking down
glucose molecules in the presence of O2
Energy in food molecules is used to
produce ATP- energy 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
• Used O2 and glucose
Raw materials= O2 and C6H12O6
End products= CO2, H2O and ATP
How do these material get into
and out of cells?
O2:
breathe in, diffused into blood and
carried to cells
C6H123O6:
food we consume, diffused into blood and
carried to cells
What is the chemical equation
for aerobic respiration?
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
• This process is also called anaerobic
• There are two types of anaerobic
respiration
– Alcoholic fermentation
– Lactic Acid Fermentation
Alcoholic Fermentation
• Glucose= 2ATP + 2CO2 + alcohol
• 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
• Glucose = 2
ATP + lactic
acid
• 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?
How are these things made?
Bacteria
Yeast
