VERIFIED.
Question :Catabolism
CORRECT ANSWER: Metabolic pathways that break
down molecules, releasing energy.
Question :Anabolism
CORRECT ANSWER: Metabolic pathways that
construct molecules, requiring energy.
Question :1st law of thermodynamics
CORRECT ANSWER: The principle of conservation of
energy. Energy can be transferred and transformed, but it cannot be created or destroyed.
Question :2nd law of thermodynamics
CORRECT ANSWER: Every energy transfer or
transformation increases the entropy of the universe.

Question :Enzymes
CORRECT ANSWER: Catalysts for chemical reactions
in living things
Question :Active site
CORRECT ANSWER: A region on an enzyme that
binds to a protein or other substance during a reaction.
Question :Induced fit hypothesis
CORRECT ANSWER: Partial binding of a substrate to
an enzyme alters the structure of the enzyme.
Question :Competitive inhibition
CORRECT ANSWER: substance that resembles the
normal substrate competes with the substrate for the active site
Question :Non-competitive inhibitor
CORRECT ANSWER: A substance that reduces the
activity of an enzyme by binding to a location remote
