4.4 Overview of Cellular Respiration
KEY CONCEPT
The overall process of cellular respiration converts
sugar into ATP using oxygen.
4.4 Overview of Cellular Respiration
Try and hold your breath for as long as you can (no cheating).
How did you feel as you were holding
your breath?
Why do you think you felt this way?
If you were to run a few miles, what
would happen to your breathing?
4.4 Overview of Cellular Respiration
How does your body use oxygen?
• Oxygen helps your body break down chemical energy that is
stored in sugars and other carbon based molecules.
• The energy produced is ATP
ATP
4.4 Overview of Cellular Respiration
Pg. 46
Compare the reactants and products. What do you notice?
4.4 Overview of Cellular Respiration
• Plants use photosynthesis to make their own food
• Animals eats other organisms as food
– Food is not the direct source of energy
- Instead we break down molecules from food to produce ATP
• Cellular respiration releases chemical energy from sugars
(produced by photosynthesis) and other carbon-based
molecules to make ATP when oxygen is present
4.4 Overview of Cellular Two
Respiration
“Stages”
• Light Dependent- ETC-Fuels
Light Independent
• Light Independent- Calvin CycleMakes Glucose
Two “Stages”
• Stage I- Kreb’s Cycle- Fuels Stage
II
• Stage II- ETC- Makes lots of ATP!
4.4 Overview of Cellular Respiration
• Cellular respiration takes place in mitochondria “the
powerhouse of the cell”
4.4 Overview of Cellular Respiration
4.4 Overview of Cellular Respiration
There are two main parts to a mitochondria:
1. Inner membrane
2. Matrix- area inside the inner membrane
Glycolysis:

4.4 Overview of Cellular Respiration
• The equation for the overall process is:
C6H12O6 + 6O2  6CO2 + 6H2O + ATP
• The reactants in photosynthesis are the same as the
products of cellular respiration.
4.4 Overview of Cellular Respiration
• Glycolysis must take place first. It happens in the cell’s
cytoplasm
– anaerobic process (does not require oxygen)
– splits glucose (from photosynthesis) into two threecarbon molecules called pyruvates
– produces two ATP molecules
“Sweet Split”

ATP
4.4 Overview of Cellular Respiration
• Cellular respiration releases chemical energy from glucose
(produced by photosynthesis) and other carbon-based
molecules to make ATP when oxygen is present
• Cellular respiration is aerobic, or requires oxygen.

Stage
I
• The Krebs cycle takes place in
the mitochondrial matrix
– 2 pyruvates enter cellular
respiration
1. Pyruvates are broken
down and ATP is made

4.4 Overview of Cellular Respiration
• Life on Earth is solar powered, and energy makes a oneway trip through an ecosystem
• Chemicals, however, are recycled
• The CO2 and H2O released by cellular respiration
are converted through photosynthesis to glucose
and O2, which are then used again in respiration
