AHSGE Objective #3
Photosynthesis and Respiration
AHSGE Objective #3

Identify reactants and products associated
with photosynthesis and cellular
respiration and the purpose of these two
processes.
List of Key Concepts:
#3-1.
 #3-2.
 #3-3.

 troph
#3-1. Greek / Latin Word Parts
auto- self
 chloro- green
 hetero- other, different
 photo- light
 -phyll leaf
 troph- feeding

#3-2. Photosynthesis
process in which light
energy is converted to
chemical energy
 carried out by autotrophs
 location: chloroplasts
 equation:
carbon dioxide + water + sunlight 
oxygen + glucose

Make sure know the
difference between reactants
and products!
#3-3. Cellular Respiration
(AKA: Aerobic Respiration)
process used to release energy in food to
make ATP / burning glucose to release
energy
 carried out by heterotrophs and
autotrophs
 location: mitochondria
 equation:
oxygen + glucose 
carbon dioxide + water + energy (ATP)

Make sure know the
difference between reactants
and products!
#3-4. Fermentation
AKA: anaerobic respiration
 respiration in the absence of oxygen /
burning glucose when oxygen is NOT
present
 may produce lactic acid or alcohol
 The process of fermentation is used while
making friendship bread 

Activity: Energy Currency of a Cell
People use currency/money to function in
today’s society in order to purchase basic
needs…In a similar fashion, a cell needs
ENERGY in order to function and survive.
 The energy required for cell processes is
produced in the mitochondria of the cell
during the process of respiration!
 During this activity you will substitute
common parts found on a typical dollar bill
(our form of currency) with characteristics
of respiration and energy/ATP production.

Activity: Energy Currency of a Cell
Replace the following…
With This…
“Federal Reserve Note”
“Energy Currency of a Cell
Note”
“The United States of
America”
Location of the process that
produces energy…
Picture of the President
Picture of Molecular Form of
ATP (pg 96 in TB)
President’s Name
Formal Full Name of ATP
