 How do we get the energy made
during photosynthesis? Since we
don’t make our own glucose from
sunlight, how do we get the
nutrients we need?
 Understand how nutrients and
energy are stored and give us the
energy we need to survive.

 Pyruvic Acid
is converted to
lactic acid
 2 ATP is formed
 Occurs in frequently in muscle
cells, during strenuous exercise
 Lactic Acid build up in muscle
cells cause muscle fatigue and
aches
 Occurs without O2
 Occurs
in the mitochondria
 Inner and Outer Membrane very
helpful!
▪ Folds make more
surface area
 CO2 formed and
 2 ATP produced
released
 Occurs
in the inner membrane of
the mitochondria
 Uses energy from the NAD+ and
FAD
 Electrons are passed from protein
to protein, slowly releasing
energy towards a final oxygen
acceptor
 Overall, 32 ATP produced.

1. Which of the following statements
describes a difference between
photosynthesis and cellular
respiration in plants?
Which of the following statements
correctly describes the processes
of photosynthesis and cellular
respiration?
A.Photosynthesis and cellular
respiration occur in the same
organelle.
B.Photosynthesis and cellular


A.Photosynthesis occurs only during the
day, whereas cellular respiration occurs
only at night.

Use Photosynthesis
 Method of converting sun energy into
chemical energy usable by cells

Autotrophs: self feeders, organisms
capable of making their own food
 Photoautotrophs: use sun energy e.g.
plants
 Chemoautotrophs: use chemical energy
e.g. bacteria




Energy enters food chains via autotrophs.
Plants and animals both use products of
photosynthesis (glucose) for metabolic fuel
Heterotrophs: must take in energy from
outside sources, cannot make their own e.g.
animals
When we take in glucose (or other carbs),
proteins, and fats-these foods don’t come
to us the way our cells can use them

The processes used to convert from
Glucose to ATP is:
 Cellular Respiration
▪ Occurs in Mitochondria
▪ Cells with Oxygen
 Fermentation
▪ Cells without Oxygen
 The
cells of all organisms can
convert the glucose from plants to
make ATP.
 Glucose
is converted to ATP in
the mitochondria of the cell.
 Breaks
down food molecules to
produce ATP - 3 stages:
 Glycolysis
 anaerobic (does not require oxygen)
 Citric
Acid Cycle
 aerobic (requires oxygen)
 Electron
 aerobic
Transport Chain



Occurs in the cytoplasm of the cell
Glucose broken down into Pyruvic Acid,
which move to the mitochondria
Produces 4 ATP, uses 2 ATP
Examine the
photograph of the
Indian pipe plant
shown.
 What can you
conclude about the
ability of the Indian
pipe plant to make its
own food? Explain
your answer.

 Cells are without oxygen
 Anaerobic process occurs
after
glycolysis
 Continues to produce ATP until
oxygen is available.
Two major types:
 Lactic Acid Fermentation
 Alcoholic Fermentation
Occurs in yeast and some bacteria
cells
 Produces CO2 and ethyl alcohol
 2 ATP formed
 Yeast in bread produces carbon
dioxide bubbles that raise the dough

Read the short article about “How Carbon
Monoxide Kills” and write two to three sentences to
answer each of the following questions.
1. What
is the main idea of the article?
2. How does the article relate to what we have
learned about Cellular Respiration?
3. What information would be most helpful is
someone is trying to determine if they are
suffering from carbon monoxide poisoning?
