"Proton hopping" essentially means that: A) an individual proton "jumps" from one electronegative group to the next. B) a free proton moves from one hydroxyl group of ionized water to the next. C) several protons move between hydrogen bonded water molecules causing the net movement of a photon over a long distance in a short time. D) individual protons are freer to move among and between water molecules in solution. E) hydronium ions are freer to move among and between water molecules ...

Once a drug reaches its target it must (blank 1) the target and vice versa and then (blank 2) to begin the process of producing the desired biological effect correct answer: Blank 1: recognize Blank 2: bind Chemical structure on drug action correct answer: drug structure, ionization, lipophilicity, reactivity, metabolism Acid/Base properties of drugs correct answer: If pH< pKa then group is protonated form If pH>pKa then group is in unprotonated form Sulfonic Acid correct a...

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...
