IN: Pg.34
Think back to cell
organelles…
• What is the function
of the mitochondria?
Pg.35 Set up Cornell notes
Title them: Chp.7-Energy
in the
Cell & Cellular Respiration
• Energy is transformed (changed into
different forms) in living things all the
time.
– For example, the chemical energy in food
is transformed into the movement of your
muscles.
– Plants take the radiant energy from the sun
and turn it into chemical energy when they
make food in photosynthesis.
• Any time energy is transformed, most of
it is “lost” to the environment as heat.
How does the cell get energy?
• The cell gets energy from carbon
containing compounds-Mostly from the
sugar, glucose (C6H12O6).
• Glucose is a high energy molecule. When
the bonds in it are broken, energy is
released.
What is the difference between an
autotroph and a heterotroph?
• Autotrophs make food through
the process of photosynthesis.
• Heterotrophs eat other
organisms to get energy.
What is cell respiration?
Occurs in the mitochondria.
C6H12O6 + O2
Glucose
+ oxygen
36ATP + H2O + CO2 + HEAT
Energy + water + carbon dioxide + heat
What is fermentation?
• Fermentation produces energy when there is no
oxygen
• Occurs in the cytoplasm.
• Two types:
– Alcoholic fermentation
Glucose
CO2 + alcohol + 2ATP
– Lactic acid fermentation
Glucose
lactic acid + 2 ATP

Friday 11-15
• Enzyme Test Retakes  everyday before
or after school till THURSDAY!
• Chp.6&7 test is next Wednesday
• INB Check Wednesday
Objective
• Explain that photosynthesis uses
light energy to convert CO2 and
water to sugar.
REVIEW
IN: Pg.38
Think back to cell organelles…
• What is the function of the chloroplast?
Set up Cornell Notes – Pg.39
• Title them: Chp.6
Photosynthesis
What is photosynthesis?
• The process in which glucose is made from
the sun’s energy.
• Occurs in the chloroplast in plants.
6H2O + 6CO2 + light
C6H12O6
Water + carbon dioxide +light
glucose
+ 6O2
+ oxygen
The steps of photosynthesis are:
• Step 1 = Chlorophyll captures light energy
from the sun
• Step 2 = Use CO2 to produce glucose
• The glucose from photosynthesis then
enters the mitochondria to complete cell
respiration (O2 present) to make energy…
• or enters the cytoplasm to complete
fermentation (no O2 present) to make
energy.

1. Label each column with the name of an energy
process. Photosynthesis Respiration
• Type of Cell -does the process occur in
autotrophic cells, heterotrophic cells or both?
• Location in Cell - what organelle or structure
does the process occur in?
• Reactants- What compounds are the raw
materials of the reaction. (What is needed?)
• Equation-write the balanced equation for the
reaction.
• Products -list the products that are made.
• Summary -summarize the entire process.
Include definition of the process and include all
the steps of the process and a brief overview
of what happens during each.
