Verified step by step guidance

Understand the role of enzymes: Enzymes are specialized proteins that act as biological catalysts, meaning they speed up chemical reactions without being consumed in the process.

Recognize that enzymes do not transport oxygen in the blood. This function is performed by hemoglobin, a protein found in red blood cells.

Clarify that enzymes do not store genetic information. Genetic information is stored in DNA and RNA molecules, not enzymes.

Note that enzymes are not primarily responsible for providing structural support to cells. Structural support is provided by proteins like collagen and cytoskeletal elements such as actin and tubulin.

Conclude that the primary role of enzymes is to act as biological catalysts, facilitating and accelerating chemical reactions necessary for life processes in the human body.
