Questions: Which of these are NOT one of the four classes of biological molecules? Nucleic Acids Lipids Carbohydrates Phosphates Amino Acids Proteins

The answer is: Phosphates

Explanation for each option:

1. Nucleic Acids: These are one of the four classes of biological molecules. They include DNA and RNA, which are essential for storing and transmitting genetic information.

2. Lipids: These are also one of the four classes of biological molecules. They include fats, oils, and steroids, and are important for energy storage, cell membrane structure, and signaling.

3. Carbohydrates: These are another class of biological molecules. They include sugars and starches, which are important for energy storage and providing structural support in cells.

4. Phosphates: These are not considered one of the four main classes of biological molecules. Phosphates are chemical groups that are part of many biological molecules, such as nucleotides (which make up nucleic acids) and phospholipids (which are a type of lipid), but they are not a class of biological molecules on their own.

5. Amino Acids: These are the building blocks of proteins, but they are not considered a separate class of biological molecules. Instead, they are subunits that make up proteins.

6. Proteins: These are one of the four classes of biological molecules. They are made up of amino acids and perform a wide range of functions in the body, including catalyzing biochemical reactions, providing structural support, and regulating processes.

Summary: Phosphates are not one of the four classes of biological molecules. The four classes are nucleic acids, lipids, carbohydrates, and proteins.
