Question

the models show the chemical structures of a fatty acid and a monosaccharide.

fatty acid
monosaccharide

complete the table to compare these structures.

	fatty acid	monosaccharide
contains oxygen
has carbon atoms arranged in a ring

Explanation:

To solve this, we analyze each row:

1. Is a building block of cellulose

• Cellulose is made of glucose (a monosaccharide). Fatty acids are for lipids, not cellulose.
• Fatty acid: No
• Monosaccharide: Yes

2. Contains oxygen

• Fatty acid has \( \text{O} \) in \( -\text{COOH} \). Monosaccharide has \( \text{O} \) in rings/OH groups.
• Fatty acid: Yes
• Monosaccharide: Yes

3. Has carbon atoms arranged in a ring

• Fatty acid has a straight carbon chain. Monosaccharide (e.g., glucose) has a ring structure.
• Fatty acid: No
• Monosaccharide: Yes

Filled Table:

	Fatty acid	Monosaccharide
Contains oxygen	Yes	Yes
Has carbon atoms arranged in a ring	No	Yes

(For the checkboxes: Mark "No" for Fatty acid and "Yes" for Monosaccharide in the first row; "Yes" for both in the second; "No" for Fatty acid and "Yes" for Monosaccharide in the third.)
