Verified step by step guidance1
Understand the role of carbohydrates in living organisms: Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1. Their primary function is to provide energy to cells.
Eliminate incorrect options: Carbohydrates are not the primary components of genetic material, as this role is fulfilled by nucleic acids (DNA and RNA).
Eliminate another incorrect option: Carbohydrates do not store genetic information; this is also a function of nucleic acids.
Consider the role of enzymes: Enzymes are proteins that catalyze biochemical reactions, not carbohydrates. Therefore, carbohydrates do not function mainly as enzymes.
Conclude the correct answer: Carbohydrates serve as the main source of energy in living organisms, as they are broken down during cellular respiration to produce ATP, the energy currency of the cell.
