THE WONDERS OF
SCIENCE…
An Alyssa and Charlotte Production
THE 3 WONDERS OF SCIENCE WE
WILL BE LEARNING ABOUT ARE . . .
Photosynthesis
 Cellular Respiration
 Fermentation
and then we will do a comparison of all 3!

PHOTOSYNTHESIS
Converts energy from the sun into food
 Oxygen + Glucose + light energy =food and energy

PHOTOSYNTHESIS
Occurs in the chlorophyll
 Only found in plant cells OR some kinds of
prokaryotic cells which contain chloroplast


CHLOROPLAST: the green pigment used to
capture the sun’s energy
PHOTOSYNTHESIS
REQUIRES:
PRODUCES:
CO2
C6H12O6
H2O
O2
Light energy (sun light)
6 CO2 + 6 H2O + light energy
C6H12O6 + 6 O2
CELLULAR RESPIRATION
The use of oxygen to release food for cell use
 Also called respiration
 Occurs in the mitochondria of ALL cells!!

CELLULAR RESPIRATION
Requires oxygen, hydrogen and ATP
 Produces reactants, products and ATP for cell energy

cH
6
O6 + 6 O2
12
+
2 ATP
6 CO2 + 6 H2o+38 ATP
FERMENTATION
Fermentation is . . .
 The releasing of energy from glucose without the
use of O2
 Also called anaerobic respiration

FERMENTATION

Occurs in the cytoplasm of prokaryotic and
fungus cells and eukaryotic muscle cells
Fungus Cells
Prokaryotic
Cell
Eukaryotic
Muscle Cells
FERMENTATION

In fungi and bacteria cells:
C6H12O6 is broken down without O2 to release . . .
4 ATP and CO2 + Alcohol
FERMENTATION

In muscle cells of multicelled organisms:
C6H12O6 is broken down without O2 to release . . .
4 ATP and Latic Acid
COMPARISON (THINGS IN COMMON)
Photosynthesis, Cellular Respiration, and
fermentation are in plant and most prokaryotic
cells.
 Cellular Respiration and fermentation both break
down glucose, are found in animal cells, release
energy, and obtain energy from ATP
 Photosynthesis and cellular respiration both are
found in plant cells

COMPARISON (DIFFERENCES)
Photosynthesis produces glucose, traps and stores
energy, obtains it’s energy from the sun, releases
O2 and takes in CO2. While Cellular Respiration
and Fermentation do not.
Cellular respiration takes in O2
Fermentation doesn’t use O2
