Verified step by step guidance

Step 1: Understand the question. The problem is asking for the term that refers to an enzyme responsible for digesting proteins. This requires knowledge of enzyme specificity and their substrates.

Step 2: Recall the function of each enzyme listed. Protease digests proteins, amylase digests carbohydrates (specifically starch), lipase digests lipids (fats), and nuclease digests nucleic acids.

Step 3: Focus on the term 'proteins' in the question. Proteins are large biomolecules made up of amino acids, and the enzyme that breaks them down is specifically called a protease.

Step 4: Eliminate incorrect options. Amylase, lipase, and nuclease do not digest proteins; they target other types of biomolecules as described in Step 2.

Step 5: Conclude that the correct term for an enzyme that digests proteins is 'Protease'. This matches the definition and function of the enzyme described in the question.
