Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. Their primary role in the body is to serve as a source of energy.

The breakdown of carbohydrates, such as glucose, occurs through cellular respiration, a process that generates ATP (adenosine triphosphate), the energy currency of the cell.

Carbohydrates are not directly involved in building genetic material, as DNA and RNA are composed of nucleotides, which include sugar molecules but are synthesized through different pathways.

Carbohydrates are also not involved in synthesizing steroid hormones, as these are derived from cholesterol, a lipid molecule.

While carbohydrates can contribute to structural components like glycoproteins and glycolipids, their primary function is to provide energy for cellular processes, making this the correct answer.
