ADMISSIONS TEST EXAM WITH
CORRECT ANSWERS
irreversible inhibitor - CORRECT ANSWERS-a substance that causes inhibition
that cannot be reversed, usually involves formation or breaking of covalent
bonds to or on the enzyme

diffraction - CORRECT ANSWERS-a change in the direction of a wave when
the wave finds an obstacle or an edge, such as an opening, occurs in
shadows

fatty acid oxidation - CORRECT ANSWERS-the metabolic breakdown of fatty
acids to acetyl CoA; also called beta oxidation

henry's law - CORRECT ANSWERS-the solubility of a gas in a liquid is directly
proportional to the partial pressure of that gas on the surface of the liquid

amber codon - CORRECT ANSWERS-stop codon (UAA, UAG, UGA)


stop codon - CORRECT ANSWERS-codon that signals to ribosomes to stop
translation (last exon in a series of exons)

partial coding sequence - CORRECT ANSWERS-portion of DNA/RNA that codes
for protein (subset of a exon)

splice acceptor site - CORRECT ANSWERS-Located at the 3' end of the intron,
terminates the intron with an AG sequence (exon/intron border)


impression management - CORRECT ANSWERS-the attempt by people to get
others to see them as they want to be seen

Mead's "Me" - CORRECT ANSWERS-the sense of self that has been learned
from interaction with others

Mead's "I" - CORRECT ANSWERS-the part of the self that is spontaneous,
impulsive, creative, and unpredictable

interpolation - CORRECT ANSWERS-prediction based on existing data (i.e.
between given data points)

,extrapolation - CORRECT ANSWERS-is an educated guess beyond the
existing data points

dipole-dipole forces - CORRECT ANSWERS-attractions between oppositely
charged regions of polar molecules

London dispersion forces - CORRECT ANSWERS-the intermolecular
attractions resulting from the constant motion of electrons and the creation
of instantaneous dipoles

electronnegativity - CORRECT ANSWERS-a measure of the ability of an atom
in a chemical compound to attract electrons

electron affinity - CORRECT ANSWERS-the energy change that occurs when
an electron is acquired by a neutral atom

critical point - CORRECT ANSWERS-the temperature and pressure at which
the gas and liquid states of a substance become identical and form one
phase

amine - CORRECT ANSWERS-R-NH2

amide - CORRECT ANSWERS-like a carboxylic acid, but with nitrogen and two
hydrogens

imine - CORRECT ANSWERS-a double bond between a carbon and a nitrogen

acetyl - CORRECT ANSWERS-methyl group bonded to a carbonyl group

acetal - CORRECT ANSWERS-a carbon atom bonded to an alkyl group, two -
OR groups, and a hydrogen

ping pong mechanism - CORRECT ANSWERS-an enzyme mechanism where a
substrate binds to the enzyme and releases a product before the second
substrate binds to the enzyme (also known as double-replacement)

ordered mechanism - CORRECT ANSWERS-an enzyme mechanism where the
substrates have to bind to the enzyme in a specific order

random order mechanism - CORRECT ANSWERS-either substrate could bind
first

splice donor site - CORRECT ANSWERS-5' end of intron (exon/intron border)

, promoter - CORRECT ANSWERS-region of DNA that indicates to an enzyme
where to bind to make RNA

signal sequence - CORRECT ANSWERS-the sequence mature RNA sequence
within a protein that directs the protein to a particular organelle

nuclear localization signal - CORRECT ANSWERS-the signal sequence for the
nucleus that enables proteins to move through pores in the nuclear envelope

glycolysis - CORRECT ANSWERS-first step in releasing the energy of glucose,
in which a molecule of glucose is broken into two molecules of pyruvic acid
(making two ATPs)

chemiosmosis - CORRECT ANSWERS-a process for synthesizing ATP using the
energy of an electrochemical gradient and the ATP synthase enzyme
(making 28 ATPs)

citric acid cycle - CORRECT ANSWERS-completes the breakdown of glucose
by oxidizing a derivative of pyruvate to carbon dioxide (making 2 ATPs)

electron transport chain - CORRECT ANSWERS-series of electron carrier
proteins that shuttle high-energy electrons during ATP-generating reactions

steroid - CORRECT ANSWERS-a type of lipid (terpene) characterized by a
carbon skeleton consisting of four rings (6-6-6-5) with various functional
groups attached

indole - CORRECT ANSWERS-a particular chemical structure found in
serotonin and LSD, has two fused rings

monoterpene - CORRECT ANSWERS-a single terpene unit, contains two
isoprene units

proximal convoluted tubule - CORRECT ANSWERS-first section of the renal
tubule that the blood flows through; reabsorption of water, ions, and all
organic nutrients

distal convoluted tubule - CORRECT ANSWERS-between the loop of Henle
and the collecting duct, selective reabsorption and secretion occur here,
most notably to regulate reabsorption of water and sodium

cortical portion of collecting duct - CORRECT ANSWERS-reabsorbs NaCl but is
impermeable to water

medullary portion of collecting duct - CORRECT ANSWERS-more permeable
to water than to NaCl (glomerular filtrate reaches highest concentration)
