Question

the models show the chemical structures of a monosaccharide and a nucleotide. monosaccharide nucleotide complete the table to compare these structures. monosaccharide nucleotide is a building block of cellulose contains oxygen has a phosphate group

Explanation:

To solve this, we analyze each row:

Row 1: Is a building block of cellulose

• Cellulose is a polysaccharide made of glucose (a monosaccharide) units. Nucleotides build nucleic acids (DNA/RNA), not cellulose.
• Monosaccharide: Yes
• Nucleotide: No

Row 2: Contains oxygen

• Monosaccharide (e.g., glucose) has \( \text{OH} \) groups (oxygen). Nucleotide has \( \text{O} \) in phosphate, sugar, etc.
• Monosaccharide: Yes
• Nucleotide: Yes

Row 3: Has a phosphate group

• Monosaccharides (like glucose) have no phosphate. Nucleotides have a phosphate group (\( \text{PO}_4^{3-} \) - like structure here).
• Monosaccharide: No
• Nucleotide: Yes

	Monosaccharide	Nucleotide
Contains oxygen	Yes	Yes
Has a phosphate group	No	Yes
