Verified step by step guidance

Step 1: Understand the function of enzymes. Enzymes are biological catalysts that speed up chemical reactions in the body. Different enzymes specialize in breaking down specific types of macromolecules.

Step 2: Recall the types of macromolecules and their corresponding enzymes. Proteins are broken down by proteases, carbohydrates by amylases, and lipids by lipases.

Step 3: Analyze the question. It asks for the enzyme complex responsible for breaking down proteins. This requires identifying the enzyme that targets proteins specifically.

Step 4: Match the enzyme to its function. Proteases are enzymes that catalyze the breakdown of proteins into smaller peptides or amino acids by hydrolyzing peptide bonds.

Step 5: Confirm the correct answer. Based on the explanation, the enzyme complex that breaks down proteins is proteases.
