I.
To grow, function, and reproduce, cells
must:
A. Create new cellular components
such as cell walls, cell
membranes, nucleic acids,
ribosomes, proteins, etc…
B.
Collect energy and convert it into
a form that is usable to do cellular
work.
II.
Cellular respiration is the process by
which organisms obtain energy from
food.
A. Glucose is the most common
source of energy
1. It comes from the
breakdown of complex
carbohydrates
B.
Making a bond stores energy
(dehydration synthesis)
C. Breaking a bond releases energy
(hydrolysis)
D.
The breakdown of food releases
energy in the form of ATP
1. Adenosine triphosphate is a
high energy molecule
2. Phosphorylation is the
transfer of energy caused by
the removal of a phosphate
molecule
3. Adenosine diphosphate is a
low energy molecule (ADP)
An analogy can be made
between the process of cellular
respiration in our cells and a car.
The mitochondria are the
engines of our cells where sugar
is burned for fuel and the
exhaust is CO2 and H2O.
III. The Energy Cycle in the Cell
C6H12O6
Low Energy
Breaking
bonds
releases
energy for a
cell to use.
Making bonds
stores energy
for a cell to
use later.
Phosphorylation
High energy
IV. Types of Cellular Respiration
A.
Anaerobic respiration is
respiration without oxygen
1.
Results in little energy
produced (2 ATP)
2.
Takes place in the cytoplasm
3.
Organisms that use
anaerobic respiration are
yeast & bacteria
a.
yeast are used to
produce CO2 to make bread
rise
b.
Yeast also makes alcohol
4.
The equation for anaerobic
respiration is:
Yeast & Bacteria
Animals
5.
Lactic acid is produced in
animal muscle cells when
there is not enough oxygen
present. This causes muscle
cramps.
TAKE THE LACTIC ACID CHALLENGE
THE WINNER RECEIVES A WAY TO
REPLENISH THE GLUCOSE USED IN
THE CHALLENGE!
Let’s take the lactic acid
challenge!!
Lean head, shoulders, lower back,
and butt against a wall, with feet
about 18 inches in front.
Keeping knees hip-width apart,
slide down the wall until you are in
a chair like position. Your legs
should not go any lower than a right
angle to the floor.
How long can YOU last?
B.
Aerobic respiration is respiration
with oxygen
1. Results in maximum energy
produced (36 ATP)
2. Takes place in the
mitochondria
3. Most organisms use aerobic
respiration
4.
The equation for aerobic
respiration is:
C6H12O6 + 6O2 = 6CO2 + 6H2O + 36 ATP

The Glucose Song
Glucose
Ah, sugar, sugar
You are my favorite fuel
From the blood-borne substrate pool
Glucose
Monosaccharide sugar
You’re sweeter than a woman’s kiss
‘Cause I need you for glycolysis
I just can’t believe the way my muscles
take you in
For you, they’ll open the door
All it takes is a little bit of insulin
To upregulate GLUT - 4
Glucose
Ah, sugar, sugar
You help me make ATP
When my predators are chasing me
Glucose
You’re an aldehyde sugar
And you’re sweeter than a woman’s kiss
‘Cause I need you for glycolysis
I just can’t believe the way my muscles
take you in
My glycogen is almost gone
A few more seconds and I’ll be rigor
mortis bound
Acidosis done me wrong!
Your sweet is turning sour, baby
I’m losing all my power, baby
I’m gonna make your muscles ache!
I’m swimming in lactate, baby
Yes, I’m swimming in lactate, baby
Now I’m drowning in lactate, baby
I’m gonna make your muscles ache!
I’m drowning in lactate, baby
Glucose
Ah, sugar, sugar
I used you up and you left me flat
Now I’ll have to get my kicks from fat
Glucose, Glucose
Sugar, Sugar,
Glucose, Glucose
Sugar, Sugar
The honeymoon is over now…..

Listen to the song again and think
about the biology behind the words.
What is this song trying to explain?
