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 Co 2 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 groups Stores HIGH energy Like a: FULLY CHARGED BATTERY

What is ADP? Adenosine DiPhosphate (ADP) It has 2 phosphate groups (rather than 3) Stores LOW energy Like 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 2 nd and 3 rd 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 3 rd 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 2 nd and 3 rd phosphate groups

Aerobic vs. Anaerobic AEROBIC RESPIRATIONANAEROBIC 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

Quick Write 1. Which molecule is like the low charged cell phone battery? Why? 1. Which molecule is like the fully charged cell phone battery? Why? 1. What represents the cell phone charger? Why? 1. 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 station At 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 activities YOUR CHOICE! As long as you have 1 from each row Use your notes and stations to help!
