Cellular Energy Part II
Photosynthesis Summary:
In the process of photosynthesis, producers like plants and algae use the energy in
_________________ to convert carbon dioxide and water into ____________ and
oxygen.
6CO
+
6H2O
+ light

C6H12O6

I. Cellular Respiration
Cells use cellular respiration to release the energy stored in the glucose (occurs in the mitochondria)
______________________ – process that allows organisms to get energy for their cells from glucose.
____________________ – organelle that performs cellular respiration. Plant and animal cells
have mitochondria.
C6H12O6
+ 6O2

6CO2
+ 6H2O
+ ATP
________
+ ________
 _______ _________ + _________+ ____________
A.
Organelle
1. What do cells take in during the process of cellular respiration?
a. Glucose and oxygen
c. water and glucose
b. carbon dioxide and water
d. oxygen and carbon dioxide
2. What do cells produce during the process of cellular respiration?
a. Glucose and oxygen
c. water and glucose
b. carbon dioxide and water
d. oxygen and carbon dioxide
3. In which organelle does the process of cellular respiration occur in?
a. Mitochondria

II. ______________________ – getting energy from food without oxygen – occurs in the cytoplasm of the cell.
A. Two types- Lactic Acid fermentation and alcoholic fermentation
1. ______________________ - produces alcohol; Bacteria and yeast eat sugar and release
alcohol as waste. Used to make bread, yogurt, cheese, pickles, beer, and wine.
Fermentation is what gives some foods their unique flavor.
C6H12O6  2CH3CH2OH +

+
2CO2
+
+
ATP
2. ________________________ - Produce lactic acid; Runners Burn  muscle cells that
don’t get enough oxygen switch to fermentation in order to get energy; lactic acid builds
up and causes burning sensation
4. Why do human cells switch from cellular respiration to fermentation?
A. To produce larger quantities of ATP
B. To produce larger quantities of glucose
C. They are not getting enough oxygen
D. They are not getting enough carbon dioxide
5. Describe a situation that has caused your cells to switch from cellular respiration to fermentation.

A. The mitochondria
C. The chloroplast
B. The cytoplasm
D. The cell membrane
