Question

the models show the chemical structures of a fatty acid and a monosaccharide. complete the table to compare these structures.

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

Explanation:

planation:

Step1: Recall cellulose composition

Cellulose is a polysaccharide made of glucose (a monosaccharide) units. So fatty - acid is not a building block of cellulose, and monosaccharide is.

Step2: Analyze oxygen presence

Looking at the structures, the fatty - acid has oxygen in the carboxyl group ($-COOH$) and the monosaccharide has multiple oxygen atoms in its hydroxyl ($-OH$) groups and ring - oxygen. So both contain oxygen.

Step3: Examine carbon - atom arrangement

The fatty - acid has a linear chain of carbon atoms, while the monosaccharide has carbon atoms arranged in a ring.

Answer:

Fatty acid	Monosaccharide
Yes	Yes
No	Yes
