Anaerobic vs. Aerobic Respiration
Do Now
With your partner: Use the slips of paper in your bag and determine if the
characteristic is a description of PHOTOSYNTHESIS or RESPIRATION
Separate them into two piles based upon their characteristics When you are done, raise your hand so I can check
When you are done: Using your notes and partner activity answer the following in
complete sentences
1. Why do animals rely on plants for survival?
2. Global warming is caused by having too many gasses such as Co2 in the air. Why might photosynthesis be helpful in reducing global warming?
What is ATP?
Adenosine TriPhosphate (ATP)Used to store and release energy.It has 3 phosphate groupsStores HIGH energy Like a: FULLY CHARGED BATTERY
What is ADP?
Adenosine DiPhosphate (ADP) It has 2 phosphate groups (rather than 3) Stores LOW energyLike a: LOW CHARGED BATTERY
How is energy released from ATP?
Energy is stored in a bond between the second and third phosphates groups.
Energy is released when the bond is broken between the 2nd and 3rd phosphate groups
In other words, energy is released when the ATP becomes ADP
How can ATP be used for energy?
ATP ADP
P
This process releases energy
How does ADP become ATP?
ADP does not have as much energy so…
ADP travels to the MITOCHONDRIA to become fully charged The 3rd Phosphate is ADDED during Cellular
Respiration
It is like: the PHONE CHARGER
How is ATP formed?
ADP + P = ATP
The chemical energy from the breakdown of glucose is used to attach “P” (a phosphate) to ADP (adenosine di-phosphate)
Where is energy stored in ATP?
Energy is stored between the 2nd and 3rd phosphate groups

Aerobic vs. Anaerobic
AEROBIC RESPIRATION
ANAEROBIC RESPIRATION
• Occurs in the presence of oxygen
• 36 ATPs are produced
•More efficient
• Occurs where there is NO oxygen
• ONLY 2 ATPs are produced
•Less efficient
• 2 types of Anaerobic Respiration: 1. Lactic Acid 2. Alcoholic Fermentation
2 Types of Anaerobic Respiration
LACTIC ACID FERMENTATION
ALCOHOLIC FERMENTATION
• Only Animals’ muscle cells
• Builds up when ATP is made with NO oxygen
• This is why your muscles get sore when you are working out hard
•EQUATION: 1 glucose CO2 + 2 ATP + LACTIC ACID
• Bacteria and yeast cells
• This is what makes bread rise!
•EQUATION:1 glucose CO2 + 2 ATP + ETHYL ALCOHOL

4. Where is the energy in ATP stored and released?
Respiration Stations
We will be passing around different stations.You will have ~4 minutes at each stationAt each station:
Read the station guide Use the reading to answer the questions on your
paper
Whiteboard Review
For each statement: Work with your partner to decide if it describes
AEROBIC or ANEAROBIC Hold your answer up toward the teacher when you’re
ready Communicate only with your partner!
1
C6H12O6 + 6O2 → 6CO2 + 6H20
2
C6H12O6 → 6CO2 + 6H20 + Lactic acid
3
A yeast cell produces alcohol
4
Occurs in the cytoplasm of the cell
5
Efficient ATP formation
6
A cheetah sprints toward prey and its muscle cells produce lactic acid
7
Results in the most energy stored
8
Requires the use of a mitochondrion
9
Yeast cells cause bread to rise
Respiration Choice Board
You must complete 3 of the 9 activitiesYOUR CHOICE! As long as you have 1 from
each row
Use your notes and stations to help!
