Which of the following statements is FALSE? A) Proteins can be structural components of cells. B) Proteins can transmit signals between cells. C) Proteins can transport molecules within cells and between cells. D) Proteins can be both hormones and hormone receptors. E) Proteins are the only biological polymer that can catalyze biochemical reactions. E

The correct option is (E). Proteins are the only biological polymer that can catalyze biochemical reactions.

Explanation:

In analysing the answer contained in option "E," it is correct that protein has the following properties:

Yes, protein is a biological polymer but not the ONLY one in the body. There are other biological polymers such as:

Carbohydrates: molecules composed of sugar monomers. They are necessary for energy storage;Lipids: water-insoluble molecules that can be classified as fats, phospholipids, waxes, and steroids. Lipids help to store energy, cushion and protect organs, insulate the body, and form cell membranes;Proteins: Biomolecules capable of forming complex structures. Proteins are composed of amino acid monomers and have a wide variety of functions including transportation of molecules and muscle movement. Collagen, hemoglobin, antibodies, and enzymes are examples of proteins.Nucleic Acids: Molecules consisting of nucleotide monomers linked together to form polynucleotide chains. DNA and RNA are examples of nucleic acids. These molecules contain instructions for protein synthesis and allow organisms to transfer genetic information from one generation to the next.Meanwhile, Proteins are Biological Polymers. Biological Polymers are large molecules composed of many similar smaller molecules linked together in a chain-like fashion. The individual smaller molecules are called monomers.Yes, Helicase is a protein Enzyme whose function is to catalyse a biological reaction.

The answer is option b.
