Food serves as a source of…
…raw materials for the cells of the body.
Food serves as a source of _______.
energy

3. The Cellular Respiration Equation
ATP
The Cellular Respiration Equation
oxygen
glucose
Water (vapor)
6O2 + C6H12O6  6H2O + 6CO2 + ATP
Carbon dioxide
Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
Cellular Respiration occurs in the _________________
Mitochondria

4. How might changes in altitude affect cellular respiration?
Check for understand #1
How might changes in altitude affect cellular respiration?
Increased altitude decreases the amount of oxygen available. With decreased oxygen cellular respiration will slow down

5. Cellular Respiration PURPOSE: To make ____ ATP!
Cellular respiration takes the _______________ found in ________ and converts it into ATP
ATP (Adenosine Triphosphate) is a type of rechargeable battery used by all cells.
Think of ATP as the energy ________ of the body
ATP!
Chemical energy
glucose
currency

6. There are 2 types of respiration:
Aerobic Respiration:
Requires oxygen
Occurs: Mitochondria
Anaerobic Respiration:
Does NOT require oxygen
Occurs: Cytoplasm

7. There are two main types of fermentation:
Alcoholic fermentation 
Lactic acid fermentation

8. F E R M N T A I O Fermentation occurs when: oxygen is not present.
Since no oxygen is required, fermentation is an __________ process.
anaerobic
The anaerobic pathways are not very efficient in transferring energy from ________ to _____.
