Guida verificata passo dopo passo1
Understand that enzymes are biological catalysts that speed up biochemical reactions without being consumed in the process.
Recall the four major types of macromolecules in living organisms: proteins, carbohydrates, lipids, and nucleic acids.
Recognize that enzymes are primarily composed of amino acids linked together in specific sequences, forming proteins.
Note that while some RNA molecules (a type of nucleic acid) can have catalytic activity (ribozymes), the vast majority of enzymes in organisms are proteins.
Conclude that the correct macromolecule type for most enzymes is protein.
