1. Biology
Unit 1 Notes:
Cellular Respiration

2. Big Question
What do plants do
when in the dark?
What do animals do?

3. (1) Cellular Respiration Definition
The reacting of
oxygen gas and sugar
(in the form of
glucose) in order to
produce “ATP”, carbon
dioxide gas, and
water.

5. (2) Cellular Respiration Equation
O2 + C6H12O6  ATP + CO2 + H2O
Carbon
Dioxide
Gas
WaterOxygen
Gas
Sugar
(Glucose)

6. (3) What is ATP?
• Full Name: Adenosine Triphosphate
• Energy storing molecule used by cells.
• Energy can be transferred in and out of its
phosphate bonds (so that cells can either
store energy, or release it and use it).

7. (4) Which Organisms & Structures Do
Cellular Respiration?
• Completed by ALL types of living
things!! (Even plants!)
• Living things use special
structures inside their cells called
“Mitochondria” to complete the
chemical reactions.

8. (5) Cellular Respiration & Energy
• The chemical potential energy from the bonds
of SUGAR is transferred to the bonds of ATP.
• Do not change the type of energy,
just move it to a different molecule for
cells to use.
•THINK 
WHY WOULD YOU GET TIRED
IF YOU DON’T EAT ENOUGH
SUGAR, OR BREATHE ENOUGH AIR?

9. (6) Cellular Respiration & Matter
• The bonds holding together
the Oxygen and Sugar
molecules are broken, and
the atoms are rearranged
to form ATP, Carbon Dioxide
and Water molecules.
• This is necessary to move
the energy to the molecule
that cells use (ATP)!
