Question

Most of a cell's molecules can be classified as belonging to one of four major classes: lipids, carbohydrates, nucleotides, and amino acids. Sort the following five molecules into one of the four major classes. Note: If you answer any part of this question incorrectly, a single red X will appear indicating that one or more of the molecules are sorted incorrectly.

Answer 1

Concepts and reasons

The concept of the general properties of biomolecules is used to solve this problem. All the molecules have different properties and structures and they all differ from one other in some respect. The lipids, amino acids, nucleotides, and carbohydrates differ from each other in properties and structure.

Fundamentals

All the cell’s molecules can be categorized as lipids, nucleotides, amino acids, and carbohydrates. Carbohydrates are polyhydroxy ketones or aldehydes. Lipids are long chain fatty acids that are insoluble in water. Nucleotides are the monomers of nucleic acids containing a nitrogen base, pentose sugar, and phosphate group. Amino acids are the compounds, which contain an amino group and a carboxylic group.

The carbohydrates given in the question are as follows:

The lipid in the given question is as follows:

The nucleotide in the given question is as follows:

The amino acid in the given question is as follows:

Ans:
