Final answer:
The four major classes of biological macromolecules are proteins, carbohydrates, lipids, and nucleic acids, each performing distinct functions essential for life. The given macromolecule is Lipid. The correct option is C.
Step-by-step explanation:
To answer what macromolecule is pictured, one would need to see the image provided. However, without the image, I can provide information on the four major classes of biological macromolecules crucial for life. These include proteins, carbohydrates, lipids, and nucleic acids.
Proteins are polymers made up of amino acids, essential in cell metabolism, structural support, and as enzymes and hormones. Carbohydrates serve as a primary energy source and offer structural support in cells. Lipids are vital for storing energy and forming cell membranes, while nucleic acids, which include DNA and RNA, are responsible for storing and transmitting genetic information.
Each macromolecule is formed through a dehydration or condensation reaction, where monomers join and release a water molecule, creating covalent bonds that result in polymers. The given macromolecule is Lipid. Therefore, The correct option is C.
