4-2 CELL ENERGY VOCABULARY
FORMULA
CO2
H 2O
C6H12O6
O2
TERM
1. PHOTOSYNTHESIS
NAME OF SUBSTANCE
Carbon dioxide
water
glucose
oxygen
DEFINITION
The process of making food using CO2,
H2O and the energy from the sunlight
FORMULA:
Carbon dioxide + water + light energy =
glucose + oxygen
Sunlight
6CO2+6H2O
C6H12O6 + 6O2
Chlorophyll
(glucose)
Raw materials: CO2 & H2O
Products: C6H12O6 & O2
2. PIGMENTS
Molecules which absorb light energy
3. CHLOROPHYLL
Green pigment in plants that traps the
Sun’s energy
4. CELLULAR RESPIRATION
The process in which animal cells use
oxygen to release
e energy from food
FORMULA:
Glucose + oxygen = carbon dioxide +
water + energy (ATP)
C6H12O6 + 6O2
6CO2+6H2O+ATP
Raw materials: C6H12O6 , O2
Products: CO2, H2O & ATP
5. FERMENTATION
The breakdown of food without the
use of oxygen; one type occurs in
muscles and produces lactic acid
No O2 used!
6. ATP
Adenosine TriPhosphate is the
molecule that stores energy
7. GLUCOSE (C6H12O6)
Simple sugar (carbohydrate) that is
produced during photosynthesis
producer
consumer
An opening on the surface of a leaf
that allows CO2 to enter the leaf
8. AUTOTROPH
9. HETEROTROPH
10. STOMA (stomata)
6CO2
+
6H2O
C6H12O6 + 6O2
Large Number= number of molecules
Small number = number of atoms
