Verified step by step guidance

Begin by identifying the primary function of hyaluronidase. Hyaluronidase is known as an enzyme, which means it catalyzes biochemical reactions.

Understand the substrate that hyaluronidase acts upon. Hyaluronidase specifically breaks down hyaluronic acid, which is a component of the extracellular matrix in connective tissues.

Differentiate between enzymes, hormones, neurotransmitters, and proteins. Enzymes like hyaluronidase facilitate chemical reactions, whereas hormones regulate physiological processes, neurotransmitters transmit signals in the nervous system, and proteins can have various functions including transport.

Consider the context of connective tissues. Hyaluronic acid is abundant in connective tissues, providing lubrication and structural support, which hyaluronidase helps to modulate by breaking it down.

Conclude by verifying the correct statement: Hyaluronidase is an enzyme that breaks down hyaluronic acid in connective tissues, distinguishing it from the other options provided.
