Question

which statement describes how enzymes and substrates are related? the enzyme influences the speed of change from substrate to product. enzymes are released as substrates in a chemical reaction. an enzyme is a special kind of substrate in a chemical reaction. substrates combine with enzymes to form reactants.

Explanation:

Enzymes are biological catalysts that increase the rate of a chemical reaction by lowering the activation - energy barrier. They act on specific substrates to convert them into products. They are not substrates themselves, nor are they released as substrates. Substrates bind to the active - site of an enzyme to form an enzyme - substrate complex, not reactants.

Answer:

The enzyme influences the speed of change from substrate to product.
