Chapter 7 - Enzymes

Denaturation

________ is a change in the structure of an enzyme that can restrict the enzyme's capacity to catalyze chemical processes.

Noncompetitive inhibitors

________ can work as feedback mechanisms, modifying the pace of chemical processes in the cell in response to changing environmental variables.

Enzymes

________ accelerate chemical processes by decreasing the reaction's activation energy.

Exergonic reactions

________ produce products with lower free energy levels than their reactants and are thus regarded energetically advantageous.

Noncompetitive

________ (or allosteric) inhibitors bind to a different place on the enzyme than the active site (called the allosteric site)

chemical reaction

To initiate a(n) ________, energy input is required to achieve a transition state.

Denaturation

________ can sometimes, but not always, be reversed when the environment returns to more ideal circumstances.

Enzymes

________ are incapable of converting an energetically unfavorable reaction into an energetically favorable one.

Enzymes

________ catalyze reactions more efficiently at specified enzyme- specific temperatures and pHs.
