BIOCHEMISTRY
1.
Biochemistry is the
CARBOHYDRATES
2.
Carbohydrate is a fancy way of saying
3.
Carbohydrates are
because they contain
4.
Name 2 things that sugars are used for
5.
Scientists also use the word
6.
Define:
Monosaccharide:
to describe sugars
Disaccharide:
Polysaccharide:
7.
is the most important sugar on earth
8.
Polysaccharides are
of
combined in a chain. They are also known as
9.
List several examples of polysaccharides and what they are used for:
LIPIDS
10.
What are lipids?
11.
Explain the structure of triglycerides:
12.
What is the difference between saturated and unsaturated fats?
13.
What are steroids used for in animals?
14.
What are waxes used for?
15.
Fats store lots of
AMINO ACID STRUCTURE
16.
Amino acids consist of a common group (which is the same in all amino acids) and a side group (which varies
between different amino acids). Name and describe the 2 smaller groups of atoms combined in the common
group. (Refer to both the paragraph and the diagram)
17.
20 amino acids are use to make
. 8 of them are called
18.
Name 3 types of “side groups” found on amino acids:
PROTEINS
19.
The chain structure of a protein is called the
structure
20.
What 2 “secondary structures” can form as a chain of amino acids begins to twist?
21.
As the chain twists more, and the twists are held in place by bonds and bridges, the protein forms its
structure.
22.
In the quaternary structure
fold together in a blob.
ENZYMES
23.
Enzymes act as
and help
24.
How are enzymes like a lock and a key?
25.
Explain the 4 steps in the process of enzyme activity:
ENZYME REGULATION
26.
List some factors that affect enzyme activity:
NUCLEIC ACIDS
27.
List several types of nucleic acids:
28.
Nucleic acids are chains of
29.
List the 5 types of nucleotides:
30.
Nucleotides are made of 3 parts:
that make a shape called a
