1. DO NOW What does photosynthesis produce?
Why are the products important?
Where do the ingredients needed for photosynthesis come from?

2. Harvesting Chemical Energy
ATP
Cellular Respiration
Harvesting Chemical Energy
ATP

3. Cellular Respiration Cellular Respiration
Biochemical process that releases the chemical energy stored in glucose and stores the energy in ATP. Occurs in the mitochondria!
The energy released from glucose is temporarily stored in the bonds of ATP. This energy is used for all life functions in all organisms.

4. Photosynthesis allows respiration to occur
CO H light  C6H12O O2
How does photosynthesis allow respiration to occur?
The products of photosynthesis allow respiration to happen! Photosynthesis gives organisms:
Glucose (stored energy)
Oxygen (helps release stored energy) 
Products
Reactants

5. Photosynthesis and Respiration Both rely on each other
Photosynthesis stores the Sun’s energy in glucose and releases oxygen as waste. BOTH plants and animals (including us) use glucose and oxygen for cellular respiration!
Photosynthesis uses the products of respiration!
Respiration uses the products of photosynthesis!

Glucose + Oxygen  ATP + Carbon Dioxide + Water
C6H12O6 + O2  ATP + CO2 + H2O
Photosynthesis?
Carbon Dioxide + Water + Light  Glucose + Oxygen

10. Regents Questions

11. Two Forms of Cellular Respiration
1. Aerobic Respiration:
Synthesizing energy WITH oxygen
2. Anaerobic Respiration:
Synthesizing energy WITHOUT oxygen
What is the purpose of cellular respiration?
Which type of cellular respiration do you think is more efficient?

12. What is the purpose of cellular respiration
What is the purpose of cellular respiration? --- To create energy for life functions Which type of cellular respiration do you think is more efficient? --- Aerobic respiration creates more ATP (energy) because of oxygen

13. Aerobic Respiration
Form of cellular respiration carried out by cells in the presence of oxygen.
Occurs in mitochondria
Purpose is to release the energy stored in organic molecules and form ATP (ready-to-use energy)
Uses Oxygen to release the maximum amount of energy stored in organic food
For this reason, aerobic respiration is much more efficient at making ATP than anaerobic respiration.
Equation:
Glucose + Oxygen  36ATP + Carbon Dioxide + Water

15. Anaerobic Cellular Respiration
Form of cellular respiration carried out by cells in the absence of oxygen.
Occurs in cell mitochondria
Purpose is to release the energy stored in organic molecules and form ATP (ready-to-use energy)
Used by certain bacteria and yeasts (fungi)
Humans also use anaerobic cellular respiration
Process used to make cheese, yogurt, baked goods, brewed goods and wines.
Two types of anaerobic cellular respiration

16. Anaerobic Respiration
1. Alcohol fermentation
Type of anaerobic respiration where ethyl alcohol is produced as a product
Glucose  2ATP + Carbon Dioxide + Ethyl alcohol
-Certain fungi (yeasts) perform this… giving us beer and wine
Without mitochondria and anaerobic respiration… there would be no alcohol.

17. Anaerobic Respiration
2. Lactic Acid formation
Type of anaerobic respiration which produces lactic acid as one of its products
Glucose  2ATP + Carbon Dioxide + lactic acid
In humans, during strenuous exercise, not enough oxygen is present in the blood (oxygen debt)
Lactic acid accumulates in muscles; leads to fatigue and pain

18. Disclaimer
Both types of anaerobic respiration are considered inefficient. The end products of both (ethyl alcohol and lactic acid) contain lots of energy that has not been effectively released for use by the cell.
