Cellular Respiration,
Photosynthesis, and
ATP
ATP = ENERGY
ATP = Adenosine Triphosphate
1 Adenosine molecule
3 phosphate groups
1 sugar called, Ribose
ATP = Adenosine Triphosphate
Adenine +
Ribose
3
PHOSPHATE
Adenosine Molecule
Phosphorous
Ribose Sugar
Making and Breaking
ATP
Energy is released when a bond
is broken between one of the
three phosphates
BROKEN BONDS
When a ATP loses a Phosphate it
becomes Adenosine Diphosphate
ATP can be made again by adding
another phosphate.
Energy is used to do this.
What do we use ATP for?
• Obtain food
• Transport materials in our body
• Eliminate waste
• Look for the remote control for
the TV
stop
What organelle makes
ATP????
•MITOCHONDRIA
Mitochondria
• Mitochondria performs cellular
respiration
• Cellular respiration AKA Aerobic
respiration
• Cellular respiration breaks down
food (glucose) to make ATP
Ingredients for Cellular
Respiration
• Mitochondria needs:
• Glucose (C6H12O6)
and
• Oxygen (O2)
Mitochondria makes
1) ATP
2) carbon dioxide (CO2)
3) H20
•
•
•
• The scientific equation is written like this:
• C6H12O6 + O2
CO2 + H2O + ATP
Where do you think
the Mitochondria gets
the oxygen and
molecule of glucose
to start with????
If you said
photosynthesis you
were correct!
Photosynthesis
Chloroplasts make glucose and
oxygen
Photosynthesis specifically happens
in the thylakoid membrane of the
chloroplast
Photosynthesis
Starts with:
•
•1) Carbon Dioxide (CO2)
•2) H20
Photosynthesis
•Photosynthesis makes:
•1) Glucose
•2) Oxygen
Photosynthesis
Equation
C02 + H20 + sun
C6H1206+O2
START: Carbon dioxide and water
Product: Glucose + Oxygen
•Think, where do
plants get the
carbon dioxide
and water
from?????
US!!!
• It’s a cycle!
Photosynthesis
Cellular Respiration
Glucose broken
Glucose is made
down
Energy of glucose
Energy is stored
if broken down
Oxygen is
Oxygen is taken in
released
Carbon dioxide Carbon dioxide is
is taken in
released
