VERIFIED CORRECT
ANSWERS GRADED A+
Substrate - CORRECT ANSWER-reactant of an enzyme-catalyzed reaction
Active Site - CORRECT ANSWER-a region on an enzyme that the substrate binds to to
activate the enzyme
Cofactor - CORRECT ANSWER-an ion or molecule that binds to an enzyme before
substrates can bind
Coenzyme - CORRECT ANSWER-nonprotein organic cofactors (vitamins)
Isozymes - CORRECT ANSWER-2 enzymes that can catalyze the same reaction
Exergonic Reactions - CORRECT ANSWER-Produces more energy than they use
Endergonic Reactions - CORRECT ANSWER-Use more energy than they produce
, Adenosine Triphosphate (ATP) - CORRECT ANSWER-an adenosine (an adenine ring and a
ribose sugar) and three phosphate groups
Phosphorylation - CORRECT ANSWER-Adding a phosphate group to ADP to form ATP
ATP synthase - CORRECT ANSWER-the enzyme that catalyzes phosphorylation
Dephosphorylation - CORRECT ANSWER-removal of a phosphate group
ATPase - CORRECT ANSWER-the enzyme that catalyzes dephosphorylation
Metabolism - CORRECT ANSWER-All of the chemical reactions that occur within an
organism
Anabolism - CORRECT ANSWER-building up
Ex. ADP phosphorylation and skin
Catabolism - CORRECT ANSWER-Breaking down
Ex. Glycolysis, break down of adipose, enzymes in stomach
Aerobic Cellular - CORRECT ANSWER-mitochondria uses oxygen to break down food and
produces ATP
Ex. Cellular respiration
