Animals have enzymes that break apart starch molecules but not cellulose, despite the fact that both are made up of glucose subunits. Which enzyme characteristic best explains this?
A) Enzyme activity is regulated.
B) Enzymes are highly specific.
C) All enzymes are proteins.
D) Enzymes usually speed up chemical reactions.
E) Enzymes are not permanently changed by the reactions they promote.

Quizplus · Accepted Answer

Enzymes are highly specific, meaning they are designed to bind to specific substrates based on the shape and chemical properties of the substrate. This specificity allows enzymes to catalyze reactions involving certain substrates but not others, even if those substrates are similar in composition, such as starch and cellulose in this case.
