Comparing Equations
Photosynthesis Equation
6CO2 + 6H2O C6H12O6 + 6O2
Cellular Respiration Equation
C6H12O6 + 6O2  6CO2 + 6H2O + 38
ATP
Mitochondria
Powerhouse of the cell
 Converts energy stored in sugars,
proteins, and lipids into ATP
 Cellular respiration is carried out in the
folded inner membrane.

Two Chemical Processes that take
place in or near the mitochondria
are:
Cellular respiration
 Fermentation

Chemical Pathways

Cellular respiration: an aerobic process
(requires the use of oxygen)

Fermentation: an anaerobic process (does
not require the use of oxygen)
Exercise
Aerobic Pathways
Anaerobic Pathways
Glycolysis
 1st
step in both cellular respiration and
fermentation
 Therefore, glycolysis occurs in both with
oxygen (aerobic) and without oxygen
(anaerobic) pathways
 It takes place in the cytoplasm
 It occurs in all living organisms
(prokaryote and eukaryote)
Glycolysis
GlucosePyruvic Acid
C6H12O62 C3H4O3
 A net of 2 ATP are made
 2 NADH (just like NADPH but for the
mitochondria) are made

Is this equation balanced?
Fermentation

After glycolysis

It occurs if oxygen is not present
Two types of fermentation: Alcohol
fermentation and lactic acid fermentation
 No ATP produced

Two Types of Fermentation
Alcohol
 Formation of alcohol
from sugar

Characteristic of
yeasts and some
bacteria
Lactic Acid
 Occurs in muscles
 Causes some muscle
pain
 Not enough O2
reaches muscles
What is Cellular Respiration?

The process that releases energy in food
with the presence of oxygen

The reaction involved in respiration are
catabolic reactions
2 Stages of Cellular Respiration
Krebs Cycle
 Electron Transport Chain

Krebs Cycle (Citric Acid Cycle)
 2nd
step in cellular respiration
 Takes place in matrix of mitochondria
 Pyruvic acid is broken down into carbon
dioxide
 3 more NADH are made
 2 FADH2 (just like ATP and NADH) are
made
 Releases 2 more ATP
Krebs Cycle
Electron Transport Chain
Occurs in the cristae of the mitochondria
 NADH and FADH2 are used
 High energy electrons that came from
Krebs cycle are used to convert ADP into
ATP
 Oxygen is a reactant and water a product

ATP Production

Glycolysis=2 ATP

Krebs=2 ATP

Electron Transport Chain= 34 ATP
Chemical Energy Produced By
Glycolysis/Cellular Respiration

A single molecule of glucose produces:
38 ATP

Fermentation Lab
Today we will be using yeast and other
household cooking materials to measure
the rate of fermentation in yeasts.
 You will be given 4 Ziploc bags to
perform your experiment. In one bag you
will put 50 mL of plain water and 10g of
yeast and in other you will put 50 mL of
10% sucrose solution and 10g of yeast.

Yeast Fermentation Lab

For your other 2 bags you will put 50 mL
of tap water, 10 g of yeast and any other
of the materials that are available to you
at the front counter.
1. Please write a question for your
experiment.
2. Please write a hypothesis for your
experiment.
3. What are the independent, dependent and
control variables?
Yeast Fermentation Lab
You must come up to me and show me
answers to questions 1, 2 and 3 before
you can actually continue with your
experiment.
 You will check your bags every 10
minutes for an hour. Please create a table
for this process.
 Fold bags over 4 times and then measure
the circumference of the bags to get an
accurate measurement of the bags.

Yeast Fermentation Lab
1. Why are we measuring the circumference
of the bags? What is being produced to
change the circumference?
2. Which of your 4 bags changed the most?
The least? Was this what you expected?
3. Was your hypothesis correct? Why or why
not?
4. How does this lab accurately depict
fermentation?

given the opportunity to do this lab again?
