Question

the models show the chemical structures of an amino acid and a monosaccharide. amino acid monosaccharide complete the table to compare these structures. amino acid monosaccharide is a building block of proteins contains nitrogen has an amino group

Explanation:

To solve this, we analyze each row:

Row 1: Is a building block of proteins

• Amino acid: Proteins are made of amino acids (yes).
• Monosaccharide: Monosaccharides build carbohydrates (no).

Row 2: Contains nitrogen

• Amino acid: Has an amino group ($-\text{NH}_2$) with N (yes).
• Monosaccharide: Formula is $\text{CH}_2\text{O}$-based, no N (no).

Row 3: Has an amino group

• Amino acid: Structure shows $-\text{NH}_2$ (yes).
• Monosaccharide: No amino group (no).

	Amino acid	Monosaccharide
Contains nitrogen	Yes	No
Has an amino group	Yes	No
