Transcript Comparing cellular respiration to photosynthesis

Warm-up
• Plants are sprawled out across the forest.
Running up the trees are squirrels.
• Name the processes that both these
organisms go through. Compare and
contrast these two processes.
Warm-up
1) What does a plant need in order to
grow?
2) What organelle do plants use to make
glucose?
3) What type of cells have mitochondria?
4) What do mitochondria break glucose
into?
Comparing cellular respiration
to photosynthesis
Cellular Respiration
How plants and
animals break glucose
Location
Found in what cells?
Relationship to
glucose
Formula
Reactants (left side of
the arrow)
Products (right side of
the arrow)
Photosynthesis
How plants make
glucose
DO NOT COPY
Photosynthesis – when plants make glucose
using sun, water, and Carbon Dioxide aka
CO2
Cellular Respiration – when plants and
animals break down glucose into water,
carbon dioxide and energy.
Cellular Respiration
• Location: Occurs in
the mitochondria
(powerhouse)
• Found in: Both plant
and animal cells
Relationship to Glucose
• In cellular respiration
the mitochondria
BREAKS glucose into
• H2O
• CO2
• ENERGY!!!
Formula for cellular respiration
Reactants!
Products!
C6H1206 + 02  H2O + CO2 + ATP energy
(glucose)
(oxygen)
(water)
(carbon dioxide)
(energy)
Photosynthesis
• Location: chloroplast
of plants (solar
panels)
• Found in: Only plants
Relationship to Glucose
• In photosynthesis the
chloroplast in plants
MAKES glucose
through sun energy
and CO2
• O2 and glucose are
made
Formula for photosynthesis
Reactants!
Products!
H2O + CO2 + sun’s energy C6H1206 + 02
(water)
(carbon dioxide)
(energy)
(glucose)
(oxygen)
Relationship to Glucose
• In cellular respiration glucose is BROKEN
• In photosynthesis glucose is MADE
Location
Cellular respiration occurs in the
mitochondria. Mitochondria is found in
both plant and animal cells.
Photosynthesis occurs in the
chloroplast. Chloroplast is only found in
plant cells.
