Factors which affect the efficiency of an enzyme

Noncompetitive inhibitors prevent an enzyme from functioning by
	1.	destroying the enzyme's substrate molecules
	2.	increasing the pH of the solution
	3.	binding to the active site and blocking the enzyme's substrate
	4.	reacting with portions of the active site (without attaching to it), causing irreparable damage

Any molecule which attaches to an enzyme's regulatory site is called
	1.	a substrate
	2.	an inhibitor
	3.	an allosteric factor
	4.	a regulatory molecule

The molecule to which an enzyme joins is called its
	1.	coenzyme
	2.	catalyst
	3.	target molecule
	4.	substrate

When an enzyme has been denatured, it has been
	1.	pulled out of shape so that it can no longer function
	2.	removed from its natural environment
	3.	deprived of its substrate molecule for a prolonged period of time
	4.	induced to bind with substrates that do not fit its active site
