Amino acid is to protein as
1. amino acid is to lipid
2. dna is to rna
3. sugar is to fat
4. simple sugar is to cellulose

Amino acids are the building blocks of proteins. The amino acids are linked by the polypeptide bonds, which form a polymer known as protein. Amino acid is to protein as:

4. Simple sugar is to cellulose

Cellulose is a polysaccharide made up of D-glucose units. Glucose is a simple sugar or monosaccharide that cannot be broken down into monomeric units. Cellulose is a polymer composed of glucose units (simple sugar) that is similar to amino acids making up proteins. The glucose units are linked by glycosidic bonds.

Reasons for incorrect answers;

Therefore, the amino acid is to protein is too simple sugar to cellulose.

To know more about simple sugars, refer to the following link:

Simple sugar to cellulose.

Explanation:

proteins are made up of several units of amino acids that are the building blocks.Several amno acids join by peptide bonding to give rise to a protein similarly several simple sugars link by glycosidic bonding to give rise to a complex sugar which is a cellulose.
