AAMC MCAT 2026 EXAM QUESTIONS AND ANSWERS
GUARANTEE A+
✔✔If the wavelength of a light beam were doubled, its frequency would be: -
✔✔c=lambdaf
✔✔If the energy of a photon is doubled, which of the following properties of the photon
will also double? - ✔✔e=hc/lambda
e=hf
✔✔An ester is prepared by the method of direct esterification using an esterase enzyme
as a catalyst. Which of the following modifications will NOT appreciably increase the
final yield of ester? - ✔✔B. increase on reactant will shift to products
C. increase in reactants will shift to products
D. removing product will cause product to freak out and get it
✔✔Question
A person pushes on a rolling cart with a force that diminishes with time because the
person must walk faster to keep up with the accelerating cart. How much work does the
person generate while pushing on the cart? - ✔✔area on force and distance graph=
work
✔✔The association observed experimentally between the expression of miRNAs and
mRNAs in AR kidney transplants indicates that miRNAs regulate the expression of
genes implicated in which type(s) of immune response(s)? - ✔✔I looked as passage
when the question clearly stated the experiment, so have to refer to the experiment for
this
Passage info: Using AR biopsy specimens, researchers measured the levels of CD3 (T
cell) mRNA and CD20 (B cell) mRNA and determined that there was a positive
correlation between these mRNA levels and the levels of miR-142-5p, miR-155, and
miR-223 but not with miR-10b, miR-30a-3p and let-7c.
So it is only referring to the adaptive immune system
✔✔Monocytes are for - ✔✔innate immunity
✔✔Lymphocytes are for - ✔✔adaptive immunity
✔✔Which is a plausible reason why participants with the attachment style investigated
are less likely to seek support from others in times of stress? - ✔✔Avoidant attachment
style- difficulties in trusting and depending on others (they are less likely to seek support
during times of stress)
Lack of worry- this is secure attachment style
concerns about others relutance to get close to them- anxious ambivalent style
, ✔✔As infants, what type of parent-infant interaction most likely occurred for the
participants? - ✔✔Avoidant attachment- no anxiety, does not want contact with the
parent
secure attachment- some attachment anxiety and and separation anxiety
strong separation anxiety + tendency to resist contact with the parent-- anxious
ambivalent
✔✔The internal working model that sets expectations about self and others described in
the study is an example of: - ✔✔insight- novel realization of a solution to a problem
critical period- individual is more receptive to learning from specific types of experiences
schemas- structures tht determine one's expectations in different contacts including
social interactions
heuristics- offer shortcuts to mental reasoning and problem solving
✔✔Which brain region will be LEAST activated when participants are completing the
tasks in the study? - ✔✔passage: identify a past event, physical and emotional stess
respoonse
parietal lobe- it intergrates sensory information and it would least likely to be used in this
case
prefrontal cortex- involved in executive functioning and decision making
amygdala- emotional encoding
✔✔The patient described in the passage is most likely using which defense
mechanism? - ✔✔Passage: pt has low self esteem and says he feels inferior towards
his successful partner, hates feeling tht wsy, stop ttending social events with partner bc
elevates feelings of inferiority but also has love for him
Projection= occurs when someone attributes unacceptale thoughts or behaviors within
themself to another person
rationalizatio-- logical explanation for unacceptable behavior
rxn formation- minimizing uncomfy thoughts or emotions by overemphasizing their
opposite.
emotion displacement- involves shifting emotion from a less to more acceptable target
✔✔The independent variable can usually be - ✔✔controlled
✔✔independent variables have to be - ✔✔experimentally manipulated
✔✔Which statement best explains the patient's behavior in terms of operant
conditioning? - ✔✔C. A positive punisher decrease the frequency of the preceding
behavior by introducing an aversive stimulus. pt's attendance of social events
decreased as a result of his event attendance leading to the elevation of feelings of
inferiority
