What is the indicator Bromothymol Blue (also known
as BTB) used for?
BTB indicator changes color in the presence of carbon dioxide

2. Cell Processes Notes

3. Cellular Respiration
CELLULAR RESPIRATION: cells use oxygen to release the energy stored in sugars, such as glucose.
This process takes place
in the mitochondria.
MIGHTY MITOCHONDRIA

4. Sugar Oxygen water carbon dioxide (ATP)
The overall reaction for cellular respiration is:
C6H12O O2  6H20 + 6CO energy
Sugar Oxygen water carbon dioxide (ATP)
Adenosine
Tri
Phosphate
ATP is the
currency of your
body
$$$

5. Two Types of Respiration
AEROBIC RESPIRATION: Glucose enters the mitochondria, where it is broken down when it combines with oxygen.
ANEROBIC RESPIRATION: (fermentation) energy is released without oxygen.
Example: Yeast cells

6. Yeast Cells Glucose is broken down into carbon dioxide,
alcohol, and A.T.P. (energy)

7. Energy and Exercise
Your muscle cells release energy by both cellular respiration (aerobic) and fermentation (anaerobic)respiration.
At rest your muscles
store energy.

8. Energy and Exercise
During prolonged exercise your muscle cells use up their stores of energy and oxygen, so the muscle cells must rely on fermentation to break down sugars.
The waste products of fermentation is lactic acid, which can cause a burning sensation in your muscles.
