What biological molecules provide energy and structural support to living organisms?A.CarbohydratesB.LipidsC.ProteinsD.Nucleic acids

All of the above options, A. Carbohydrates, B. Lipids, C. Proteins, and D. Nucleic acids, provide energy and structural support to living organisms.

A. Carbohydrates: These are the body's main source of energy. They can be broken down quickly and efficiently to provide immediate energy.

B. Lipids: These are used for long-term energy storage. They also provide insulation and protection for organs.

C. Proteins: These are essential for building and repairing tissues, making enzymes, hormones and other body chemicals. They are also an important building block of bones, muscles, cartilage, skin, and blood.

D. Nucleic acids: These are the building blocks of DNA and RNA, which carry genetic information for the production of proteins. They don't typically provide energy, but they support the structure of cells and help to facilitate processes like protein synthesis.
