Vocabulary:
Metabolism
Using energy to
build or break
down molecules in
which energy is
stored
Anabolism: build up
Catabolism: break down
Definitions:
ATP
Adenosine
Triphosphate
A high energy
molecule. Releases
energy when one
of its three
phosphates breaks
off forming ADP.
1. What happens during this
process?
Light energy is
converted into chemical
energy/food/glucose
2. What types of cells perform
this process?
1. Plants (green parts)
2. Algae
3. Some Bacteria
3. Where in the cell does this
process occur?
• Chloroplasts
– Thylakoids:
photosynthetic sac
– Granum/Grana:
stacks of thylakoids
– Stroma: clear liquid
4. Does this process build or
break down molecules?
• Both!
• Builds glucose & O2
• Breaks down H2O
and ATP/energy
5. What are the steps of
photosynthesis?
1. Pigments (chlorophyll) capture sunlight
in the Thylakoid.
Pigment: light absorbing molecule
5. What are the steps of
photosynthesis?
2. Light Reactions: (occurs in thylakoid membrane)
Light energy is converted to chemical energy
(ATP). H2O is used and O2 is released.
NADPH is also produced to be
used for glucose formation
5. What are the steps of
photosynthesis?
3. Dark Reactions (Calvin Cycle): (in stroma)
ATP powers the formation of glucose using
CO2
ATP and NADPH is used to
power glucose formation
6. What is the equation for
photosynthesis?
6CO2 + 6H2O + sunlight energy  C6H12O6 + 6O2
carbon
dioxide
water
glucose
oxygen
gas
6. What is the equation for
photosynthesis?
#7
#8
9. What is the main goal of this
process
Make glucose (sugar/food) for the cell
10. What factors affect this
process?

Notecard Homework
On a notecard, write the equation:
Photosynthesis
6CO2 + 6H2O + sunlight energy  C6H12O6 + 6O2
6Carbon dioxide + 6Water + sunlight makes Glucose + 6Oxygen
Find, recite equation correctly, and get signatures
from 3 LFU staff (extra points if one of the people is
a principal)
1. What happens during this
process?
Chemical energy in food is converted
into a form that cells can use (called
ATP)
2. What types of cells perform
this process?
All cells in all living things
3. Where in the cell does this
process occur??
Mitochondria
4. Does this process build or
break down molecules?
• Both!
• Builds ATP/Energy
• Breaks down
glucose & O2
5. What are the basic steps of
this process?
1. Glycolysis:
- Glucose  pyruvate
- 2 ATP made
- Occurs in cytoplasm
5. What are the basic steps of
this process?
2. Kreb’s Cycle:
- produce 2 ATP and CO2
-occurs in mitochondria
5. What are the basic steps of
this process?
3. Electron Transport Chain:
- Needs O2
- produces 32 ATP, and H20
- occurs in mitochondria
6. What is the equation for cell
respiration?
#7
#8
9. What is the main goal of this
process
Make ATP/Energy
10. What factors affect this
process?
• Oxygen
– Aerobic respiration: With Oxygen
• makes 36 ATP
– Anaerobic respiration: Without Oxygen
• makes 2 ATP
10. continued
• Fermentation
– Lactic Acid Fermentation:
occurs in muscles during
rapid exercise (causes
soreness)
– Alcoholic Fermentation:
occurs in yeast and bacteria
Only 2 ATP
produced!!
