Cellular Respiration
Its how our cells release energy from food!
BrainPOP: Cellular Respiration
Do you remember???
 What types of organisms do photosynthesis?
 Why do plants do photosynthesis?
 What are the reactants (what goes in)?
 What are the products (what goes out)?
 Which plant organelle is the site of
photosynthesis?
 How do animals get their energy?
 How do they get food?
 Which organelle releases energy from food?
Cellular Respiration
The process by which cells
release
from glucose (sugar).
This process happens in BOTH
PLANT and ANIMAL cells!
Where do plants
and animals obtain glucose?
FOOD!
Animals get it from the food they eat!
Plants get it from the food they make!
Glucose is the most common
sugar found in food!
C6H12O6
Besides glucose, what else do cells
use for cellular respiration?
Oxygen
How do we get oxygen?
Breathing
energy
oxygen
food
breathing
Two Stages
of Cellular
Respiration
Use your
textbooks…
page 382!
Stage 1:
Stage 2:
In the cytoplasm
In the mitochondria
 Glucose is broken
down into smaller
molecules
 A small amount of
energy is released
 The smaller molecules
react and produce
carbon dioxide, water
and large amounts of
energy.
What are the reactants and products
of cellular respiration?
C6H12O6 + 6O2
glucose
+
oxygen
6CO2 + 6H2O + energy
carbon dioxide
+
water

Is matter
conserved after
this chemical
reaction?
energy
Cellular Respiration Equation
This energy is also
known as ATP!
Reactants (what goes in)
Products (what comes out)

Description
1. Releases energy from food
2. Makes food energy for the organism
3. Performed by autotrophs (plants) only
4. Produces carbon dioxide
5. Produces glucose and oxygen
6. Occurs in the chloroplast
7. Occurs in the mitochondrion
