Where does energy come from?
What are some ways organisms use
energy?
Are there different types of energy?
ATP-
adenosine triphosphate
Is made up of:
Adenosine
Ribose
Phosphate group
Storing Energy
ADP- adenosine diphosphate
Only has 2 phosphate groups
When a cell has energy to store, it
can store small amounts of it by
adding a phosphate group to ADP
Releasing Energy
ATP- has 3 phosphate groups
When a cell requires energy, a cell
can add or subtract phosphate
groups
How Do We Get Energy From
ATP?
By breaking the
high- energy
bonds between
the last two
phosphates in
ATP
How does that happen?
• ATP-ase catalyzes the
decomposition of ATP from ADP
• ATPsynthase does the opposite
and catalyzes the production of
ATP from ADP
Energy Molecule
ATPsynthase

ATP ases
What can cell use this
energy for?
1. Active transport
2. Cell movement
3. Making proteins
Any thing else????
Facts:
Cells use glucose to store energy
1 glucose molecule stores 90x the
energy of 1 molecule of ATP
Let’s get started!
1. Grab a textbook
2. Turn to Quick lab on page 198 (What is
the waste product produced by photosynthesis)
3. Read the procedure and with a partner
make a prediction about what you will
observe from the plant using the
information from the web quest.
4. Do I have a volunteer???
Do Now
Answer the following questions:
1. In addition to light and chlorophyll, photosynthesis
requires
a. water and oxygen
b. water and sugars
c. oxygen and carbon dioxide
d. water and carbon dioxide
2. Write the basic equation for photosynthesis using the
molecular formulas and the names of the starting and final
substances of the process.
1. Give an example of an autotroph and heterotroph in
this picture.
2. How is photosynthesis important to these organisms?
What is photosynthesis?
Plants,
• Process ___
bacteria
algae
use to make
their own food.
• Which category do plants fall
under. Autotroph or heterotroph?
a. Autotrophs
_______ : organisms, like plants,
that use light energy from the sun
to produce their own food Because plants
can “manufacture” their own energy directly, they are
self-sufficient.
Heterotrophs
b. ____________:
organisms that
obtain energy from foods they
consume
All other forms of life, such as humans, animals, insects
and even bacteria, depend on other living things for
food.
Plant leaves contain
Chlorophyll
_____________
(green color) makes
photosynthesis possible, it captures
the sunlight. What organelle in a
plant can you find___________?
Chloroplast
Leaf Anatomy- where are
chloroplasts located?
What is in the chloroplast
that captures light?
What does a plant need to perform
sunlight is
photosynthesis? The ______
water
CO2
combined with ______,
_______
and
nutrients from the soil.
oCO2
plant
The __________
processes the
glucose
ingredients and makes _______
(plant food) and ________.
oxygen
O2
What is the equation for
photosynthesis?
sunlight
Reactants
Carbon dioxide + Water
Products
→ Glucose + Oxygen

2 Parts to Photosynthesis
Light dependent reaction:
requires light for process to proceed
Light independent reaction:
(Calvin cycle) does not require light

PHOTOSYNTHESIS
• What affects photosynthesis?
– Light intensity: as light increases, rate
of photosynthesis increases
PHOTOSYNTHESIS
• What affects photosynthesis?
– Carbon Dioxide: As CO2 increases, rate
of photosynthesis increases
PHOTOSYNTHESIS
• What affects photosynthesis?
– Temperature:
• Temperature Low = Rate of photosynthesis
low
• Temperature Increases = Rate of
photosynthesis increases
• If temperature too hot, rate drops
