A block slides down a frictionless incline from rest. As it descends, which statement is true?
A competitive inhibitor is added to an enzyme-catalyzed reaction. Which change is observed?
A. Km increases, Vmax unchanged
B. Km decreases, Vmax decreases
C. Km unchanged, Vmax decreases
D. Km increases, Vmax decreases
A. Competitive inhibition raises apparent Km, and Vmax is recovered at high [S]
A person assumes a stranger who cut them off in traffic is a rude person, ignoring possible situational causes. This is an example of:
A. Self-serving bias
B. Fundamental attribution error
C. Actor-observer bias
D. Confirmation bias
B. Overweighting dispositional explanations and underweighting situational ones is the fundamental attribution error

buffer contains a weak acid HA and its conjugate base A⁻ in equal concentrations. How does the pH of the buffer compare to the pKa of HA?
Epinephrine binds a G protein-coupled receptor on a liver cell and raises cAMP. What is the effect on glycogen metabolism?
A. Glycogen phosphorylase activated, glycogen synthase inhibited
B. Glycogen phosphorylase inhibited, glycogen synthase activated
C. Both enzymes activated
D. Both enzymes inhibited
A. Epinephrine triggers the cAMP/PKA cascade, which promotes glycogenolysis and inhibits glycogen synthesis.
Which sociological perspective views society as a system of interdependent parts that work together to maintain stability?
A. Conflict theory
B. Symbolic interactionism
C. Structural functionalism
D. Social constructionism
C. Structural functionalism emphasizes interdependent parts and stability. Conflict theory emphasizes inequality and competition.
Intransigent means

Blood flows from the aorta into the capillary beds. The capillaries are individually much narrower, yet blood velocity is far lower in the capillaries than in the aorta. What best explains this?
B. The total cross-sectional area of all capillaries combined is much greater than that of the aortaCorrect
A deletion removes the TATA box from a gene’s promoter. What is the most likely result?
A. A protein with an altered amino acid sequence
B. A truncated protein
C. A reduced amount of structurally normal protein
D. A frameshift in the mRNA
C. The promoter affects transcription initiation, not coding sequence, so less normal protein is made.
Under the elaboration likelihood model, a person who is highly motivated and able to think carefully about a message is most persuaded by:
A. Speaker attractiveness
B. Message length
C. The quality of the arguments
D. Peripheral cues
C. The central route processes argument quality. Peripheral cues dominate when motivation or ability is low.

In a galvanic cell at standard conditions, the reaction quotient Q is increased by adding more product. Which of the following correctly describes the effect?
Intestinal epithelial cells absorb glucose via SGLT (Na+/glucose symporter). What happens to glucose uptake if the Na+/K+ ATPase is inhibited?
A. No change, since SGLT uses ATP directly
B. Decreases, since the Na+ gradient dissipates
C. Increases, since intracellular Na+ rises
D. Decreases, since GLUT2 is blocked
B. SGLT is secondary active transport, so it depends on the Na+ gradient the pump maintains.
A patient with bilateral hippocampal damage cannot form new declarative memories but improves at a mirror-tracing task across sessions, without remembering the sessions. This best supports the claim that:
A. Procedural memory depends on structures other than the hippocampus
B. Procedural and declarative memory share the same neural substrates
C. Mirror tracing is a form of explicit memory
D. The hippocampus is required for all learning
A. Procedural/implicit memory relies on the basal ganglia and cerebellum, so it can survive hippocampal damage.
Quixotic means
What's exceedingly idealistic, unrealistic, and impractical?
