Guida verificata passo dopo passo1
Recall the four major classes of biomolecules: carbohydrates, lipids, proteins, and nucleic acids.
Understand that ATP (adenosine triphosphate) consists of an adenine base, a ribose sugar, and three phosphate groups.
Recognize that a molecule composed of a nitrogenous base, a sugar, and phosphate groups is classified as a nucleotide.
Note that ATP is specifically a nucleoside triphosphate because it has three phosphate groups attached to the nucleoside (adenosine).
Conclude that ATP is best classified as a nucleotide (a nucleoside triphosphate), not as a triglyceride, polysaccharide, or polypeptide.
