AP Biology Discussion Notes
Friday 12/11/2015
Goals for the Day
• Begin understanding the process of
cellular respiration
Question of the day 12/11
What is the equation for cellular respiration?
Chemical Equation for
Cell Respiration
C6H12O6 + O2 
CO2 + H2O + ATP
• Label the reactants & Products
• What organisms do cellular respiration?
Why (What is the KEY product)?
Cellular respiration
• Do ALL organisms need to do this?
• Do ALL organisms do it the same way?
