How Cells Convert Food Into Energy
Cellular Respiration occurs in ALL
cells (plant/animal/etc.) ALL THE
TIME!
Definition: Cellular Respiration is the process
by which cells break down fuels ( mainly
glucose) to free up the energy required for
cellular functions.
Aerobic respiration:
Anaerobic respiration:
uses oxygen
does not use oxygen.
Requires Oxygen!
No Oxygen!

Cellular Respiration
While you are watching the
video, make a T-table or Venn
diagram to compare & contrast
aerobic and anaerobic cellular
respiration
Today’s Task
Work
at the lab tables with your
group. Finalize your Ttables/Venn diagrams.
Complete the
Photosynthesis/Cellular
Respiration worksheet
All due tomorrow!
Warm-Up
Why
is cellular respiration
important for all living things?
What is the relationship
between photosynthesis and
cellular respiration?
Cellular Respiration – 2 Types
Aerobic Respiration

 Learning
Target (write it in your
notebook): I can describe the
importance of biosynthesis and
breakdown reactions for supplying
energy and organic molecules for
all organisms
 Update your TOC
Some Vocab:
Metabolism:
the chemical reactions
that take place in a cell or organism.
Biosynthesis: reactions that build
larger, more complex molecules
(require energy)
Breakdown: reactions that break
down larger molecules into smaller
molecules (free up energy)
What are some examples of these 2
types of metabolic reactions?
 Where
do plants get the energy
they need to survive?
 Photosynthesis
converts light energy
into chemical energy stored in
glucose.
 What
do plants do with the glucose they
create during photosynthesis?

Some questions:
 Create
a well- labeled diagram, ENDING
with a chicken drumstick, showing where
the CARBON in the chicken leg originally
came from: (Where does the carbon start
and how does it get into the drumstick?)
 List 3 examples of (each) biosynthesis and
breakdown reactions.
 Why are biosynthesis and breakdown
reactions important for all organisms?
Additional Info From Mz. R…
Metabolism
There are 2 types of metabolism: biosynthesis and
decomposition.
Biosynthesis:
Builds up (synthesizes) new, larger, more complex molecules
such as starch or DNA, proteins, build tissue and blood, etc.
Consumes free energy
Enables organisms to grow and maintain structure.
Decomposition:
Larger molecules break down into smaller ones, such as
glycogen to glucose, and glucose into CO2 & water.
Energy becomes available.
