ADP, ATP and
Cellular
Respiration
Engage: Let’s Recap
Photosynthesis


Plants absorb sunlight and use its energy to
grow directly.
Autotrophic plants use chloroplasts, and the
process of photosynthesis, to capture the
energy from sunlight and store it by creating
sugar (glucose) molecules.
1. Write out the chemical equation for
photosynthesis. Using the magazines
supplied, cut out pictures/symbols
that can represent the reactants and
products of photosynthesis.
However…
It is important for you to realize that
photosynthesis alone can not sustain life.
 Plants, or other living things, can not
stay alive if this was all that happened.
Remember, glucose is like a storage
house for energy, storing the chemical
energy obtained from the sun.
 How is all of this energy released from
storage???

EXPLORE: CELLULAR
RESPIRATION

Respiration releases the chemical energy
stored in glucose, which is used by the
cells to carry out their life activities
(growing, moving, etc.).
2.Create a labeled diagram showing
how photosynthesis and
respiration are related using
pictures cut out from a
magazine.
Sunlight (radiant
energy)
is Transformed
through the process of
Photosynthesis in
Green Plants
Transforming the
radiant energy into
GLUCOSE (chemical
energy)
which can be
Respired by
Plants & Animals
to Transform chemical
energy
Into other forms
Required to continue
living.
RESPIRATION
–
Respiration is NOT the same as what
we call breathing!
– Respiration is a chemical reaction…
3. Write out what you think the
equation for respiration looks
like.
What Is ATP?
Energy used by all Cells
Adenosine Triphosphate
Organic molecule containing highenergy Phosphate bonds
Chemical Structure of ATP
Draw
This !
3 Phosphates
Adenine Base
Ribose Sugar
What Does ATP Do for
You?
It supplies YOU with ENERGY!
How Do We Get Energy From
ATP?
By breaking
the highenergy bonds
between the
last two
phosphates
in ATP
When is ATP Made in the
Body?
During a
Process called
Cellular
Respiration
that takes
place in both
Plants &
Animals
Overall Equation for
Cellular Respiration
C6H12O6
+ 6O2
YIELDS
6CO2 + 6H20 + e- + 36-38ATP’s
Where Does Cellular
Respiration Take Place?
 It
actually
takes place in
two parts of
the cell:
Glycolysis occurs
in the Cytoplasm
Krebs Cycle &
ETC Take place in
the Mitochondria
