Which is the only macromolecule to contain Phosphorus atoms? Carbohydrates Amino Acids Nucleic Acids Lipids

## Step 1<br />The question asks us to identify the macromolecule that contains Phosphorus atoms. The options provided are Carbohydrates, Amino Acids, Nucleic Acids, and Lipids.<br /><br />## Step 2<br />We need to understand the composition of each macromolecule. Carbohydrates are composed of carbon, hydrogen, and oxygen atoms. Amino Acids, which are the building blocks of proteins, consist of carbon, hydrogen, oxygen, and nitrogen atoms. Lipids, which include fats, oils, and waxes, are composed of carbon, hydrogen, and oxygen atoms.<br /><br />## Step 3<br />Nucleic Acids, on the other hand, are composed of carbon, hydrogen, oxygen, nitrogen, and Phosphorus atoms. They are the only macromolecules among the options provided that contain Phosphorus atoms.
