All _ are proteins and in this way they control the whole metabolism of the cell.
Correct answer: C. Enzymes
- A. Hormones
- B. Antibodies
- C. Enzymes
- D. Immunoglobulins
Explanation
Enzymes are proteins that play a crucial role in controlling the entire metabolism of the cell. They function as biological catalysts, accelerating the chemical reactions necessary for various cellular processes, thus ensuring the cell's metabolic pathways operate efficiently. In contrast, hormones, while sometimes proteins, are primarily signaling molecules; antibodies and immunoglobulins are focused on immune response, not metabolism.

About Biological Molecules
The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
