Explanation:

Step1: Define reactants in enzyme - catalyzed reaction

Reactants in an enzyme - catalyzed reaction are called substrates.

Step2: Classify enzymes by macromolecule type

Enzymes are categorized as proteins (a type of macromolecule).

Step3: Define biological catalyst

A biological catalyst (like an enzyme) is a substance that speeds up a biochemical reaction without being consumed in the reaction.

Step4: Identify parts of the diagram

A is the enzyme, B is the active site, C is the substrate, D is the enzyme - substrate complex, E is the product.

Answer:

1. Substrates
2. Proteins
3. A substance that speeds up a biochemical reaction without being consumed in the reaction.
4. A = Enzyme, B = Active site, C = Substrate, D = Enzyme - substrate complex, E = Product
