Which acronym is used for classifying different types of enzymes?

• A. LEC
• B. PHEOC
• C. I SMASH Rocks
• D. DABDA

Answer: (A)

The correct acronym for classifying different types of enzymes is "I SMASH Rocks." This mnemonic is commonly used in biochemistry to help remember the six main classes of enzymes based on their function:

• I: Isomerases - enzymes that catalyze the rearrangement of molecules.

• S: Synthases (or Synthetases) - enzymes that catalyze the synthesis of larger molecules from smaller units.

• M: Lyases - enzymes that facilitate the breaking of various chemical bonds by means other than hydrolysis and oxidation, often resulting in the formation of a double bond or a ring structure.

• A: Hydrolases - enzymes that catalyze the cleavage of bonds through the addition of water.

• S: Transferases - enzymes that transfer functional groups from one molecule to another.

• H: Oxidoreductases - enzymes that catalyze oxidation-reduction reactions.

• R: Ligases - enzymes that join two molecules together with covalent bonds.

This comprehensive coverage of enzyme classes in "I SMASH Rocks" makes it a valuable tool for students preparing for the MCAT and other biology-related exams. Other options, while they may suggest different
