D) Enzymes emerge changed from the reactions they catalyze.

Question

Quizplus · Accepted Answer

An enzyme's function depends on its three-dimensional shape. The shape of the enzyme determines its specificity and ability to bind to its substrate, and any changes in the shape can affect its activity.

Answer: B is incorrect because enzymes are typically specific to certain substrates.

Answer: C is incorrect because enzymes are not used up in chemical reactions; they are catalysts that facilitate the reaction without being consumed themselves.

Answer: D is incorrect because enzymes emerge unchanged from the reactions they catalyze. The enzyme may assist the reaction, but it is not altered by the reaction.
