UKY Bio 152 Exam 1 – Danley Questions
and Answers
cell label - Correct Answers -
Biological Molecule - Correct Answers -a molecule made by a living organism that
contains carbon as its backbone, usually 2 or more carbons
(proteins, carbohydrates, nucleic acids, lipids)
Monomer - Correct Answers -molecule made of a single building block, very simple
Polymer - Correct Answers -a larger molecule that is made of of 2 or more monomers
Hydrophilic - Correct Answers -types of molecules that are water loving and dissolve in
water easily
Hydrophobic - Correct Answers -types of molecules that do not dissolve in water well
Function - Correct Answers -the job or what that molecule does
Saturated - Correct Answers -each carbon along the backbone has the max number of
hydrogens hanging off
, Unsaturated - Correct Answers -one or more carbons along the backbone have let go of
hydrogens and formed one or more double bonds with neighbor carbon which results in
it having less than the maximum number of hydrogens
Hydrocarbon - Correct Answers -a long backbone of carbons with nothing but
hydrogens hang off... no overall charge and hydrophobic
Carbohydrates - Correct Answers -- repeating units of C-H20
- provide structural support and identification
- hydrophilic
Lipids - Correct Answers -- long chains of C-H2 (hydrocarbons)
- hydrophobic
- signals molecules
Fatty Acid Tails - Correct Answers -- sub class of lipids
- can be saturated or unsaturated
Microfilaments - Correct Answers -(actin) and is used to stiffen and give cell shape and
assist with end/exocytosis events
Microtubules - Correct Answers -(tubulin) and is used as roadways within the cell and
assist with movement of chromosomes during mitosis/meiosis
Intermediate filaments - Correct Answers -mix of complex polymers
proteins/carbohydrates and they are used as the glue of cytoskeleton to hold organelles
in place
Prokaryote Genome/Cell - Correct Answers -- DNA is one continuous circular strand
- DNA replication start at the point of attachment and proceeds through the entire loop
Proteins - Correct Answers -- made from long chains of amino acids (monomers) that
have undergone guided folding and assembly processing
- typically hydrophilic
receptors, structure, transport
Nucleic Acids - Correct Answers -- made from nucleotide monomers
- each nucleotide is made from 3 sub units (nitrogen base, carbon sugar, phosphate
group)
- phosphate group gives these molecules a negative charge
- hydrophilic
- DNA & ATP
- energy carrier and stores information for the cell
Metabolism - Correct Answers -The energetic sum of all chemical reactions in a cell
(anabolic + catabolic)
