AAMC EXAM 2023-2024

Le Chatelier’s Principle –  correct answer  States that if a stress is applied to a system at equilibrium, the system shifts in the direction that relieves the stress.

Bose-Einstein Principle –  correct answer states that a collection of atoms cooled close to absolute zero will coalesce into a single quantum state.

Heisenberg uncertainty principle –  correct answer  States that one cannot know an object’s momentum and position with absolute certainty.

Pauli Exclusion Principle – The correct answer  States that two or more identical fermions, e.g. electrons, cannot occupy the same quantum state.

The reaction between NADH and ubiquinone is exergonic, but when catalyzed by Na+-NQR, it does not generate much heat in vivo. What factor accounts for this difference? –  correct answer  The movement of a charged particle against its concentration gradient is energetically costly. Coupling the two processes, the redox reaction between NADH and ubiquinone and the movement of Na+ up a concentration gradient makes the overall process less exothermic.
