Question

Which biomolecule is made of long chains of amino acids; functions include enzymes­which speeds the rate of chemical reactions, structural components in cells, mechanical functions in muscles and cytoskeleton, cell signaling, and immune response; provides structure and helps with chemical reactions 1. Protein
2. Lipids
3. Carbohydrate
4. Nucleic Acid

Answer 1

Answer:

The correct option is 1. Protein

Explanation:

Proteins are polymers whose monomers are amino acids. Proteins perform very varied functions in living organisms. They constitute the physical support of the body, in the metabolism, they serve as hormones, carriers of vitamins, oxygen and carbon dioxide and as enzymes (biological catalysts). They also carry out cell signaling and defense activities. Thus, the skin and nails are made of keratin, the silk of fibroin, tendons and cartilage of collagen, these are some examples of structural proteins. The hormones insulin and glucagon are examples of proteins with regulatory function, these hormones are responsible for regulating blood glucose levels. Antibodies are also proteins responsible for the defense of the organism.
