Unit C PLO C1-C6 Rev Q’s
1.
CARBON and HYDROGEN
2.
COVALENT BONDS
3.
Carbon needs to share with another 4 extra
electrons to meet the Octet rule.
4.
POLYMER
5.
Condensation Synthesis
AKA – Dehydration Synthesis
6.
HYDROLYSIS – "Water Breaking"
7.
FOUR (4)
8.
No water molecules are produced, but rather 9
molecules of water are used up to hydrolyze the
9 bonds between the 10 Glucoses.
LO C-2
1.
Proteins are built out of AMINO ACIDS
2.
The specific monosaccharide required is GLUCOSE
3.
NUCLEIC ACIDS – DNA and RNA
4.
A "POLYSACCHARIDE"
LO C-3
1.
2.
Carbon, Hydrogen and Oxygen.
CnH2nOn or CH2O.
Ex C6H12O6 , C5H10O5
3.
The most simple sugars are the one unit sugars
known as MONOSACCHARIDES. A
DISSACCHARIDE is also considered to be a pretty
simple sugar.
LO - C-4
1.
2.
C6H12O6
3.
A HEXOSE (6 carbon sugar)
4.
A PENTOSE (5 carbon sugar)
5.
Some monosaccharides would include GLUCOSE,
FRUCTOSE, GALACTOSE.
6.
A disaccharide is a molecule formed from when
two monosaccharides join together.
7.
Maltose, Sucrose and Lactose.
8.
MALTOSE = GLUCOSE – GLUCOSE
SUCROSE = GLUCOSE – FRUCTOSE
LACTOSE = GLUCOSE –GALACTOSE
9.
The three main complex carbohydrates are : STARCH,
GLYCOGEN and CELLULOSE.
10. See Picture below
11. A Pentose sugar is one that has FIVE CARBONS.
For example C5H10O5 = Ribose
Or C5H10O4 = Deoxyribose
12. A HEXOSE sugar would be GLUCOSE, FRUCTOSE,
GALACTOSE are all C6H12O6.
LO C-5
1.
Starch is a glucose STORAGE (energy) molecule found
in plants. Plants make their glucose and then they
store it for later.
2.
Glycogen is a glucose STORAGE (energy) molecule
found in animals. Animals take in carbohydrates from
their diet and then the excess glucose is stored in
muscle and liver cells as a complex carbohydrate.
3.
Both cellulose and starch are made out of glucose
molecules being bonded together, but the orientation
of the glucose molecules and bond angles are different.
5.Glycogen will have far more side chains than what you
would see in starch.
7. Cellulose is also known as dietary fiber. Fiber plays an
important role in cleaning the intestines and preventing
colon cancer. Controls blood cholesterol levels.

3.
Carbohydrates are primarily used as an energy source
in most living things especially animals.
Hydrolysis
Carbohydrates in plants are used to provide energy
(glucose and starch), but also for structural parts of a
plant (cellulose).
