Complete the text. The lipids in cells are made ut of building blocks. __ are building blocks that can be linked together with other small molecules to make larger, more complex compounds,including fats and phospholipids. Simple sugars Fatty acids Amino acids Nucleotides

## Step 1<br />The problem is asking us to identify the building blocks of lipids in cells. Lipids are a type of organic compound that are primarily composed of carbon, hydrogen, and oxygen. They are a major component of the cell membrane and are involved in many other cellular processes.<br /><br />## Step 2<br />The options provided are simple sugars, fatty acids, amino acids, and nucleotides. Each of these is a type of molecule that serves as a building block for different types of compounds.<br /><br />## Step 3<br />Simple sugars are the building blocks of carbohydrates, not lipids. Amino acids are the building blocks of proteins, not lipids. Nucleotides are the building blocks of nucleic acids, not lipids.<br /><br />## Step 4<br />Fatty acids, on the other hand, are the building blocks of lipids. They can be linked together with other small molecules to form larger, more complex compounds, including fats and phospholipids.
