AP BIOLOGY - ENERGY AND
ENZYMES TEST REVIEW GUIDE
QUESTIONS AND ANSWERS
lactase - ANSWER-aids lactose digestion
maltase - ANSWER-breaks down sugar from various grains
enzymes in warm temperature - ANSWER-molecules move faster, collide harder and
more often, more likely to react
enzymes in hot temperature - ANSWER-denature-lose 3D shape
enzymes in low temperature - ANSWER-move slowly, collide rarely, enzymes work
slowly
metabolism - ANSWER-the totality of an organism's chemical reactions, consisting of
catabollic and anabolic pathways, which manage the material and energy resources
of the organism
metabolic pathway - ANSWER-a series of chemical reactions that either builds a
complex molecule (anabolic pathway) or breaks down a complex molecule to simpler
molecules (catabolic pathway)
catabolic pathway - ANSWER-a metabolic pathway that releases energy by breaking
down complex molecules to simpler molecules. hydrolysis
anabolic pathway - ANSWER-a metabolic pathway that consumes energy to
synthesize a complex molecule from simpler molecules. dehydration
kinetic energy - ANSWER-the energy associated with the relative motion of objects;
moving matter can perform work by imparting motion to other matter
heat (thermal) energy - ANSWER-that total amount of kinetic energy due to the
random motion of atoms or molecules in a body of matter; also called thermal
energy; energy in its most random form
potential energy - ANSWER-the energy that matter possesses as a result of its
location or spatial arrangement (structure)
chemical energy - ANSWER-energy available in molecules for release in a chemical
reaction; a forma of potential energy
first law of thermodynamics - ANSWER-the principle of conservation of energy;
energy can be transferred and transformed, but it cannot be created or destroyed.
energy in the universe is constant.
