AP BIOLOGY EXAM QUESTIONS AND
ALL COMPLETE ANSWERS.
Water characteristics - Answer polar, cohesion (hold together), adhesion (hold to another substance),
surface tension, specific heat, heat of vaporization



Surface Tension - Answer A measure of how difficult it is to stretch or break the surface of a liquid



Specific Heat - Answer amount of heat absorbed or lost to change temperature by 1C



Heat of Vaporization - Answer the quantity of heat required to convert 1 from liquid to gas



Water polarity - Answer uneven sharing of electrons that produces a negative charge near the oxygen
atom and positive charges near each hydrogen atom



Water properties - Answer solvent, cohesive, thermal



Organic Chemistry - Answer the study of carbon compounds



Hydroxyl - Answer OH-, alcohol/ethanol



Carbonyl - Answer C=O, aldehyde, keytone



Carboxyl - Answer O=C-OH, carboxylic acid as in acetic acid



Amino - Answer H-N-H, amine as in tryptophan

Globular proteins - Answer chunk, soluble (amylase, insulin, hemoglobin, immunoglobin, transport
pumps)



Anabolic reactions - Answer build complex molecules from simpler ones, endergonic, biosynthetic
(example: photosynthesis)



Catabolic reactions - Answer breakdown of molecules, exergonic, degradative (example: cellular
respiration)



First Law of Thermodynamics - Answer Energy can be transferred and transformed, but it cannot be
