Understand the role of enzymes in biological systems: Enzymes are biological molecules that speed up chemical reactions in cells.
Identify the type of biomolecule enzymes are: Enzymes are primarily proteins, which are made up of long chains of amino acids.
Differentiate enzymes from other biomolecules: Unlike lipids, nucleic acids, and carbohydrates, enzymes specifically function as catalysts in biochemical reactions.
Recognize the function of enzymes: Enzymes lower the activation energy required for reactions, allowing them to proceed more quickly and efficiently.
Conclude that enzymes are proteins that catalyze biochemical reactions, distinguishing them from other types of biomolecules like lipids, nucleic acids, and carbohydrates.
