Module 1 Exam Questions and
Answers 100% PASS
cell—ANSWER-the smallest, basic biological unit of life
macromolecules—ANSWER-complex molecules that are composed of smaller subunits
4 types of macromolecules—ANSWER-(1) Proteins (2) Nucleic acids (3) Lipids and (4)
Polysaccharides
polymer—ANSWER-a large molecule comprised of many smaller subunits
proteins—ANSWER-polymers of amino acids and are the most abundant form of
macromolecule
function of proteinsffprot—ANSWER-facilitate the movement of materials in or out of a cell
function of proteins—ANSWER-can act as enzymes that catalyze, or speed up, biochemical
processes
function of proteins—ANSWER-play a structural role or enable movement
amino acids—ANSWER-the order and length in which ________________ are assembled
give rise to different protein sizes, structures and functions
primary structure—ANSWER-unique sequence of amino acids
, titin—ANSWER-33k amino acids, largest known protein
essential amino acids—ANSWER-9 amino acids that the human body can't produce—they
must instead be taken in from the environment through other sources (i.e.) the food you
eat.
nucleic acids—ANSWER-chemical molecules that carry genetic information within the cell
DNA and RNA—ANSWER-two major types of nucleic acids
DNA—ANSWER-contains a vast amount of hereditary information and is responsible for the
inheritable characteristics of living organisms
RNA—ANSWER-responsible for deciphering the hereditary information in DNA and using it
to synthesize proteins, capable of leaving the nucleu
DNA molecules—ANSWER-coiled and twisted into a highly compact form to fit in the nucleus
of the cell
nucleotides—ANSWER-are the building blocks for DNA . There are three parts to it:
Nitrogen base
Deoxyribose (sugar)
Phosphate group
Types of nucleotides—ANSWER-purines and pyrimidines
purine base—ANSWER-adenine or guanine
pyrimidine base—ANSWER-cytosine and thymine
