BELL WORK:
Copy the bolded part of the question and write
your answer.
Like complex carbohydrates, proteins are biomolecules that serve
many functions and can be chemically broken down and
restructured. Both proteins and complex carbohydrates are which
of the following?
A
B
C
D
Polymers of smaller subunits
Sequences of sugars
Lipids of large molecules
Nucleotides of DNA
CO: I will compare the products
and reactants of photosynthesis
and cellular respiration.
LO: I will write notes. I will discuss
photosynthesis & cellular
respiration with a partner.
Anticipation Thoughts…
1. Thigmotropism is a plant’s response to gravity.
2. Transpiration is how plants absorb water
through their roots.
3. The stomata allows water into the leaves.
4. The guard cells open and close the stomata at
the most opportune times of day for the plant.
5. Plants produce glucose during photosynthesis.
Cellular Energy
• Energy :the ability to do work
• Most energy comes from the sun in the
form of light.
• All energy
leaves the
Earth in the
form of
heat.
• Adenosine triphosphate (ATP) is the chemical
that cells use to store and release energy.
• The energy in ATP is stored in the bonds between
the elements.
What biomolecule does ATP look like?
II. Photosynthesis
• To perform photosynthesis, plants need:
1. sunlight (energy source)
2. water
3. carbon dioxide
These are called the reactants.
• After photosynthesis, the plant has produced:
1. Glucose (molecule that the plant uses to
produce energy)
2. Oxygen (given off through the leaves)
These are called the products.
The equation of photosynthesis is:
6CO2 + 6H2O + sunlight  C6H1206 + 6O2
carbon dioxide + water + energy  glucose + oxygen
Talk to your partner:
Where do plants get carbon dioxide?
How do plants take in water?
Photosynthesis occurs in an organelle in the leaves.
Chloroplasts: organelle where photosynthesis takes
place
Chlorophyll: pigment in chloroplasts, makes plants
green
III. Cellular Respiration
• Cellular
respiration:
the process
that releases
energy by
breaking down
glucose.
• Cellular respiration occurs in the mitochondria
of plant and animal cells.
• Cellular respiration makes 36 ATP molecules
• The remaining energy is lost as heat.
Mitochondria
The formula for cellular respiration is:
6O2 + C6H12O6  6CO2 + 6H2O + Energy
oxygen + glucose  carbon dioxide + water + ATP
Cellular respiration requires oxygen and
glucose and gives off carbon dioxide,
water, and energy.
Talk to your partner:
If humans do not make our own
food in photosynthesis, how do
we get glucose for cellular
respiration?
SAGE & SCRIBE
1. You will be working with the person next to you.
2. First round:
– Partner A/C: Describe photosynthesis in WORDS
– Partner B/D: Write the EQUATION for
photosynthesis
3. Second round:
– Partner B/D: Say the cellular respiration EQUATION
– Partner A/C: Write the WORDS for cellular
respiration
At the bottom of your page,
choose ONE equation and draw
pictures to represent each of the
products and reactants.
