What are enzymes?

Proteins that catalyze biochemical reactions
Structures that provide structural support
Molecules involved in transporting chemicals across cell membranes
Specialized cells that carry out specific functions

The correct answer is: Proteins that catalyze biochemical reactions

Enzymes are proteins that are known to be biological catalysts, meaning that they can speed up chemical reactions without being consumed or changed in the process. This makes option A the correct answer. Option B refers to structures, which are not the same as proteins, and do not have the ability to catalyze reactions. Option C mentions molecules that are involved in transport, which also do not have the same function as enzymes. Option D mentions specialized cells, which are not the same as proteins and do not have the same function as enzymes. Therefore, these options are incorrect in reference to what enzymes are.
