HUMAN ANATOMY EXAM 1 WITH VERIFIED
QUESTIONS AND ANSWERS|| ALREADY
GRADED A+
What are Monounsaturated Fatty Acids ? - ANSWER-Fatty acids with one
double bond present
Define Polyunsaturated fatty acids - ANSWER-Fatty acids with two or more
double bonds present
What are Phospholipids make up ? - ANSWER--Glycerol molecule
-2 fatty acids
-Phosphate Group
Why do Phospholipids stand out from most lipids - ANSWER-The
phospholipid are apart of the phosphate group .
Phospholipids are structured to interact with both hydrophobic and hydrophilic
molecules.
What is the structure of the sterol nucleus - ANSWER-One, 5 carbon ring
attached to three, 6 carbon rings.
A sterol nucleus is hydrophobic (nonpolar)
,What molecular building block are proteins made of ? - ANSWER-amino acids
What type of bond holds the building blocks together ? - ANSWER-peptide
bond
What is the general structure of an amino acid ? - ANSWER-1. Amino Group
2. Carboxylic acid group
3. one functional group
How many amino acids are there ? - ANSWER-20 and they are all different
What does the word catalyst mean? - ANSWER-a substance that increases the
rate of a chemical reaction without itself undergoing any permanent chemical
change.
What does it mean to be a biological catalyst - ANSWER-Enzymes are soluble
protein molecules speed up chemical reactions in cells. These reactions include
respiration, photosynthesis and making new proteins. For this reason enzymes
are sometimes called biological catalysts.
How are enzymes named? - ANSWER-Enzymes are named according to their
function or their function or substrate
What 3 letters does an enzyme name usually end with - ANSWER-ASE
What is meant by the term conformational structure? - ANSWER-A very
specific 3-dimentional structure
Can an enzyme function without correctconformational structure - ANSWER-
NO
, Info on Active Site of an Enzyme - ANSWER-Binding site for substrate
substrate converted to product at active site
Info on Denaturation - ANSWER-Disruption of conformational structure
loss of enzyme activity due to loss of proper active site shape.
Compare Co-factor and Co-enzyme - ANSWER-Both deal with enzymes
How many types of linkage are there, Name them. - ANSWER-there are 5
1.Dipeptide
2. Tripeptide
3. Oligopeptide
4.Polypeptide
5.Proteins
Define Dipeptide - ANSWER-a chain of 2 amino acids
Define Tripeptide - ANSWER-A chain of 3 amino acids
Define Oligopeptide - ANSWER-Composed of 4 to 10 amino acids
Define Polypeptide - ANSWER-Composed of 10 to 60 amino acids
