MODELS OF ENZYME ACTION

Question 1

is the relatively small part of an enzyme’s structure that is actually involved in catalysis.

Answer 1

active site

Question 2

three-dimensional entity formed by groups that come
from different parts of the protein chain(s); these groups are brought together by the

Answer 2

Folding and bending

Question 3

location in the enzyme

Answer 3

“crevicelike”

Question 4

is the intermediate reaction species that is formed when a
substrate binds to the active site of an enzyme

Answer 4

enzyme–substrate complex

Question 5

he active site in the enzyme has a fixed, rigid geometrical conformation.

Answer 5

Lock-and-Key Model

Question 6

allows for small changes in the shape or geometry of the
active site of an enzyme to accommodate a substrate

Answer 6

Induced-Fit Model

Question 7

The forces that draw the substrate into the active site are many of the same forces
that maintain tertiary structure in the folding of peptide chains

Answer 7

Electrostatic interactions and hydrophobic interactions
