Warm-up Questions:
Energy equations and graphs.
• If someone is studying the effects
of light on the growth of a plant,
what process are they likely
studying?
• In which process that takes place in
the mitochondria are the energy
bonds of glucose transferred to the
phosphate bonds in ATP?
CELLULAR RESPIRATION
EQUATION
The reactants are the parts that combine
together on the right side of the
equation, they form the products. They
are what goes in. In respiration, the
reactants are one glucose molecule and
The products are the result of the reactants
six molecules of oxygen.
going through the process. They are on the left
side of the equation and are what is produced.
The products are what come out after the
process. The products of respiration are six
molecules of water, 6 molecules of carbon
dioxide and about 38 ATP (energy).
C6H12O4 + 6O2
Reactants
6CO2 + 6H2O + Energy (about 38 ATP)

PHOTOSYNTHESIS EQUATION
The reactants in the photosynthesis
equation are light, six molecules of
carbon dioxide, and 6 molecules of water. The products of photosynthesis are
one glucose molecule and six oxygen
molecules.
The products of photosynthesis are
what fuel the cellular respiration in
order for energy to be produced. The
CO2 and O2 enter and exit the plants
through openings called stoma or
stomata.

EXTRAS
Plant cells carry out photosynthesis
within the chloroplasts.
The chlorophyll within the
chloroplasts are what gives the plant its
green color as well as what stores the
light energy from the sun to be used
during photosynthesis.
Mitochondria are responsible
for the process of cellular
respiration to produce energy,
thus the name powerhouse of
the cell.
Organic molecules occur
naturally in nature (oxygen, etc)
and inorganic are produced
(glucose).
GRAPHING PHOTOSYNTHESIS
AND CELLULAR RESPIRATION
As the intensity of light increases, so does the rate of photosynthesis. Plants
take in more carbon dioxide with more light, and release carbon dioxide if the
light level is too low.
CO2 Exchange
At point C, the rate of cellular
respiration is equal to the rate
of photosynthesis.
