MCAT Review Final Test Questions with
Complete Solutions (Latest 2025/2026).
cell differentiation is involved in what kind of signaling? - CORRECT ANSWERS mRNA
correspondence interference theory - CORRECT ANSWERS it's when someone recognizes a
trait/behavior of yours and assumes other characteristics based on that one trait.
trypsin - CORRECT ANSWERS lyses peptide bonds
adrenal medulla
vs adrenal cortex - CORRECT ANSWERS medulla = epi, norepi (catecholamines)
cortex = cortisol and aldosterone
volt units - CORRECT ANSWERS J/C
farad units - CORRECT ANSWERS C/V, electric charge
when BP increases, what happens to pulse and urine? - CORRECT ANSWERS both increase
in the urinary system, what occurs when there is high blood pressure? - CORRECT ANSWERS
high BP
more blood pushing, greater blood volume
increase urine output
for urine, what is the ideal composition? - CORRECT ANSWERS no protein, just HUNK
(hydrogen, urea, nitrogen, potassium)
what part of the brain controls HR? - CORRECT ANSWERS brain stem (medulla oblogata)
math tip for solving logs - CORRECT ANSWERS switch sign of exponent
take exponent and add or subtract it by first number moved back a tenth
hydrogen bonds: donor vs acceptor - CORRECT ANSWERS donor = H
acceptor = electronegative atom
columns on the periodic table have the same what? - CORRECT ANSWERS same properties
due to their valence electrons
therefore, you can compare elements based on their column
fractional distillation + bubbles = ? - CORRECT ANSWERS superheating
bubbles break surface tension and lower pressure
color in organic chemistry - CORRECT ANSWERS extended pi system with alternating double
bonds
d orbitals**
,ADH - CORRECT ANSWERS antidiuretic hormone (vasopressin)
makes collecting duct more permeable, body reabsorbs water, makes you pee and concentrates urine,
BP increases
when you see cancer, think of ? - CORRECT ANSWERS mutation
BP equation - CORRECT ANSWERS resistance x CO
CO = HR x SV
vasoconstriction - CORRECT ANSWERS narrows vessels
restricts flow
increases BP
what occurs when you faint? - CORRECT ANSWERS decrease of BP, vasodilation
large Ka - CORRECT ANSWERS strong acid
buffers - CORRECT ANSWERS want to stay at pka = pH
do indicators affect reactions? - CORRECT ANSWERS no
sperm is very rich in what organelle? - CORRECT ANSWERS mitochondria
albumin - CORRECT ANSWERS protein in blood; maintains the proper amount of water in the
blood
size of eukaryotic and prokaryotic ribosomes - CORRECT ANSWERS 80 (60 and 40) and 70 (30,
50) respectively
smaller ksp - CORRECT ANSWERS lower solubility
big ksp - CORRECT ANSWERS more soluble
when does precipitate form? - CORRECT ANSWERS Q>Ksp
titration pH values - CORRECT ANSWERS weak base, strong acid <7
weak base, weak acid = 7
strong base, weak acid > 7
lewis acid - CORRECT ANSWERS accepts pair of electrons
lewis base - CORRECT ANSWERS donates pair of electrons

arrhenius base - CORRECT ANSWERS produces OH-
optics: diverging lens - CORRECT ANSWERS DDUV = diverging, diminishing, upright, virtual
optics: converging and diverging lenses and mirrors - CORRECT ANSWERS converging
(inverted real): convex lens, concave mirror
diverging: concave lens, convex mirror
myopia - CORRECT ANSWERS nearsightedness
need concave lens, diverge, f-
hyperobia - CORRECT ANSWERS farsighted
convex lens, converge, f+
basic amino acids - CORRECT ANSWERS lysine
histidine
arginine
isomerase - CORRECT ANSWERS rearrangement of atoms, moving carbons
thin layer chromatography - CORRECT ANSWERS separates molecules based on polarity
james lange theory of emotion - CORRECT ANSWERS
shacter singer theory of emotion - CORRECT ANSWERS
canon bard theory of emotion - CORRECT ANSWERS physiological reaction and the emotion
are assumed to occur at the same time
merkel cells - CORRECT ANSWERS touch receptors in the skin
pacinian cells - CORRECT ANSWERS vibration
ruffini endings - CORRECT ANSWERS respond to stretch
transformation - CORRECT ANSWERS swallowing genetic information
transduction - CORRECT ANSWERS injection, requiring a virus
conjugation - CORRECT ANSWERS sex pilli, F factor
translocation - CORRECT ANSWERS movement of genes
autosomes - CORRECT ANSWERS every other chromosomes
define a species - CORRECT ANSWERS ability to produce offspring
