Photosynthesis
Photosynthesis
• The process by which
light energy is absorbed,
in plants, and converted
to the chemical energy
of glucose - C6H12O6
Photosynthesis
•The following is the chemical reaction of Photosynthesis:
6CO2 + 6H2O ���� C6H12O6 + 6O2
6 carbon + 6 waters ���� 1 Glucose + 6 oxygen
dioxides
Sunlight
What is Needed What is Produced
Cellular Respiration• The process whereby chemical
energy stored in the form of
glucose (simple sugar –
C6H12O6) is converted into the
chemical energy of ATP
(adenosine triphosphate). This
process occurs in the
Mitochondria of the cell
Cellular Respiration• Glucose molecules are the
fuel for cellular respiration.
• The chemical reaction is the
following:
stuff needed ���� stuff given off
C6H12O6 + 6O2 ���� 6CO2 + 6H2O + 36ATP
1 Glucose+ 6 oxygen����6 carbon+6 water+energy
dioxides
OVERVIEW OF
PHOTOSYNTHESIS• Where does photosynthesis take
place?
– In the leaves of plants
– Cells contains chloroplasts(organelles that capture sunlight)
– The chlorophyll molecule within the chloroplast is actually responsible for capturing light energy.
OVERVIEW OF
PHOTOSYNTHESIS• The reactions of photosynthesis
take place in two main stages:
1. Light Reaction (Light Dependent Reaction)
• capture sunlight energy
• Splits H2O to release O2
2. Calvin Cycle (Light Independent Reaction)
• use energy from light reaction to fixCO2 into carbohydrates (C6H12O6)
STOP! REFLECTION
• For the next 5 minutes, answer the
question in the box at the bottom of
your notes.
• Write 3-4 level 3 questions on the
left side of the page
3 Steps of Cellular
Respiration (Aerobic)
1. Glycolysis
2. Krebs Cycle (Citric Acid Cycle)
3. Electron Transport Chain (System)
Step 1 – Glycolysis
• Each Glucose molecule is broken down & produces 2 ATP (oxygen is not required)
• Occurs in the cytoplasm
These are
the steps of
Glycolysis.
(Be sure to
know them
for the next
test)
Just
Kidding!!!
Step 2 – Krebs Cycle
•2 more ATP are
formed
(oxygen is required)
• CO2 is given off

Step 3Electron Transport Chain
• Oxygen is required to
ultimately form 32 ATP
The End Product• For every glucose molecule
that goes through cellular
respiration, ~36 ATP are
produced
1 C6H12O6 = 36 ATP
Fermentation
Fermentation: a cell process in which
glucose is broken down in the absence
of oxygen. 2 ATP are produced.
• The two most common forms of
fermentation are:
1. alcoholic fermentation (yeast and
bacteria)
2. Lactic acid fermentation (animal cells)
