SUCCESS
Active Site - CORRECT ANSWER -The specific portion of an enzyme
that attaches to the substrate by means of weak chemical bonds.
Induced Fit - CORRECT ANSWER -the change in shape of the active site
of an enzyme so that it binds more snugly to the substrate, induced by entry
of the substrate.
An enzyme's activity can be affected by - CORRECT ANSWER -
Temperature, pH, and chemicals that influence the enzyme.
Cofactors - CORRECT ANSWER -Non-protein molecule or ion that is
required for the proper functioning of an enzyme, can be permanently bound
to the active site or may bind loosely and reversibly along the substrate
during catalysis
, Coenzyme - CORRECT ANSWER -An organic molecule serving as a
cofactor. Most vitamins function in important metabolic reactions.
Competitive Inhibitors - CORRECT ANSWER -A substance that reduces
the activity of an enzyme by entering the active site in place of the substrate
whose structure it mimics.
Noncompetitive Inhibitors - CORRECT ANSWER -A substance that
reduces the activity of an enzyme by binding to a location remote from the
active site, changing its shape so that it no longer binds to the substrate.
Allosteric regulation - CORRECT ANSWER -the binding of a regulatory
molecule to a protein at one site that affects the function of the protein at a
different site.
Cooperativity - CORRECT ANSWER -A kind of allosteric regulation
whereby a shape change in one subunit of a protein caused by substrate
binding is transmitted to all the others, facilitating binding of subsequent
substrate molecules.
Feedback Inhibition - CORRECT ANSWER -A method of metabolic
control in which the end product of a metabolic pathway acts as an inhibitor
of an enzyme within that pathway.
