Where does Cellular
Respiration occur?
Mitochondria
What are the three
steps in Cellular
Respiration?
1.Glycolysis
2.KREBS cycle
3.Electron Transport Chain (ETC)
Where does Glycolysis
take place?
Cytoplasm
What two respirations
occur?
Anaerobic and Aerobic
If after Glycolysis there is
no oxygen present what
process will begin?
Fermentation
Photosynthesis
Photosynthesis is the conversion of
light energy into _____ energy
stored in organic compounds.
Chemical
What is the equation for
Photosynthesis?
CO2+H2O=C6H12O6+6O2
Where does photosynthesis happen?
Within the chloroplast of
the PLANT cell.
What pigment is located
within the chloroplasts of
plant cells?
Chlorophyll
What are the two groups of
reactions and how do they
work?
Light Dependent- Trap the energy
from the sunlight
Calvin Cycle- Uses energy from light
reactions to produce sugars. Carbon
dioxide and water are needed with
light, sugar is produced and oxygen
is given off.
Where do light reactions take place?
Thylakoid
Where does the Calvin Cycle occur?
(Aka=Dark Reaction)
the Stroma
What are three factors affecting
Photosynthesis?
Water Amounts, Temperature, and
Intensity of Light

Energy
and Life
Where do autotrophs get their
energy?
They get it directly from the sun. Unlike
Autotrophs, heterotrophs are unable to
produce organic substances from inorganic
ones. They rely on an organic source of
carbon that has originated as part of another
living organism.
What do heterotrophs do?
They eat food to obtain their energy and also
uses organic carbon for growth
What makes up a molecule
of ATP?
Chemical compounds
Vocabulary
1. Autotrophs: organisms get energy ______ from
the sun.
2. Heterotrophs: organisms that eat food to

3. ATP: Adenosine Triphosphate, only releases
energy (________ compound).
4. ADP: Adenosine Diphosphate, stores or releases
energy (_____ power).
Vocabulary cont.
5. Photosynthesis: The conversion of _____ energy
into _____ energy stored in organic compounds.
6. Chlorophyll: Main pigments in ________
(absorbs all colors of light, and reflects back
green).

Vocabulary cont.
9. Light Reactions: Trap ___ from the sunlight.
Occurs in the ______.
10. Calvin Cycle: Also known as _______,
Produces ______ and occurs in the stroma.

15. Aerobic: Cells must contain glucose, oxygen, and ______
in order to make ATP, CO2 and H2O.
