Question

12 multiple choice 1 point identify the molecule in the diagram above: glucose (monosaccharide) fatty acid nucleotide amino acid clear my selection

Explanation:

Step1: Analyze glucose structure

Glucose has a ring - like structure with multiple hydroxyl ($-OH$) groups and an aldehyde or ketone group, not this long - chain with a carboxyl group only.

Step2: Analyze fatty acid structure

Fatty acids have a long hydrocarbon chain with a carboxyl group ($-COOH$) at one end, which matches the given structure.

Step3: Analyze nucleotide structure

Nucleotides consist of a nitrogen - containing base, a five - carbon sugar, and a phosphate group, not this structure.

Step4: Analyze amino acid structure

Amino acids have both an amino group ($-NH_2$) and a carboxyl group ($-COOH$) along with a side chain, and this structure lacks an amino group.

Answer:

B. fatty acid
