Question 1

denaturization

Answer 1

when the weak bonds that maintain the native shape of the apoenzyme are broken

causes distorted enzyme shape and prevents attachment of the substrate to the active site

Question 2

competitive inhibition

Answer 2

inhibits enzyme activity by supplying a molecule that resembles the enzyme’s normal substrate; “mimic”

occupies the active site, preventing the actual substrate from bindind

Question 3

noncompetitive inhibition

Answer 3

molecules bind to regulatory site and slows down enzymatic activity once a certain concentration of products is reached

Question 4

enzyme repression

Answer 4

genetic apparatus responsible for replacing enzymes is automatically suppressed

Question 5

enzyme induction

Answer 5

enzymes appear only when suitable substrates are present

Question 6

cyclic form

Answer 6

the starting molecule is regenerated to initiate another turn of the cycle
