Photosynthesis & Cellular
Respiration Notes
June 2, 2016
How do we grow a plant?
But is that all????
I. Photosynthesis
A. Where does this happen in the cell?
1. Chloroplasts
B.
What type(s) of cell(s) go through
this?
1. Plants
Chlorophyll inside
C. Process of Photosynthesis
What goes in?
Sunlight (light Energy)
Water
H2O
Carbon Dioxide
CO2
Photosynthesis
What comes out?
Sunlight
(Light Energy)
Glucose
C6H12O6
Water
H2O
Oxygen
Carbon Dioxide
CO2
O2
D. Chemical Reaction



Let’s write the chemical equation on
the board!!
What are the reactants, What are the
products?
What type of energy transformations
are going on?
– Light Energy into Chemical Energy
Reaction



CO2 + H2O + light O2 + C6H12O6
But it’s not balanced
6 CO2 + 6 H2O + light 6 O2 + C6H12O6
Reactants
Products
II. Cellular Respiration
A. Where does this occur in the cell?
1. Occurs in Mitochondria
B. What type(s) of cell(s) go through
this?
1. ALL cells must perform this reaction
– Not like photosynthesis that only occurs
in autotrophs
– It’s why we breathe
C. Process of Cell Respiration
Carbon Dioxide
Glucose
CO2
C6H12O6
Water
H2O
Oxygen
O2
Energy
D. Chemical Reaction



Let’s draw the chemical formula on the
board!!
What are the reactants, What are the
products?
What type of energy transformations
are going on?
– Chemical Energy (Food) into Chemical
Energy (ATP)
Reaction



C6H12O6 + O2  CO2 + H2O + Energy
But it’s not balanced
C6H12O6 + 6 O2  6CO2 + 6H2O + Energy

Products
E. Relationship between Photosynthesis
& Cellular Respiration
Two Types of Respiration

You are currently
1. This process is also
taking in oxygen and
known as Aerobic
burning sugars within
Respiration. Why?
the mitochondria to
a. Oxygen is present
release chemical
which allows your
energy.
cells to burn
glucose into
energy much
more efficiently
What would happen if your cells were
deprived of oxygen?? Would they still be
able to burn glucose to make energy??
YES!!
2. Anaerobic Respiration: Respiration
with NO OXYGEN PRESENT
a. Example: Fermentation in body cells
1. Long distance runners often create an
anaerobic environment for their cells
2. Not a very energy efficient process
3. Bad side effect is produced: Lactic Acid
(muscle cramps)
b. A different example of
fermentation
1.
Breweries rely on this process
a. Yeast cells need energy to survive, so
they will breakdown sugars in anaerobic
conditions and the byproduct is alcohol
b. How do you know CO2 is produced?
c. Fermentation Basics
1.
2.
3.
Anaerobic
Animals produce lactic acid and CO2
Plants produce ethyl alcohol and CO2
Efficiency of Types of Cell
Respiration
 Aerobic
respiration yields at
least 36 ATP
 Anaerobic nets a measly 2
ATP
