Which of the following statements about the active site of an enzyme is correct?
A
The active site can bind to any molecule regardless of its shape.
B
The active site is a rigid structure that does not change shape.
C
The active site is specific to the substrate it binds.
D
The active site is located on the enzyme's surface and is always exposed.
Verified step by step guidance1
Understand that enzymes are biological catalysts that speed up chemical reactions in the body by lowering the activation energy required for the reaction.
Recognize that the active site of an enzyme is the region where substrate molecules bind and undergo a chemical reaction.
Learn that the active site is highly specific to its substrate, meaning it can only bind to molecules that fit its shape, similar to a lock and key model.
Note that the active site is not a rigid structure; it can undergo slight changes in shape to accommodate the substrate, a concept known as induced fit.
Realize that the active site is typically located on the enzyme's surface, but it is not always exposed; it may be hidden until the enzyme is in the right environment or until the substrate approaches.
