Matching Carbohydrates to Structural and Functional Features

Steps:

• Identify key carbohydrates: amylopectin (branched starch), sucrose (disaccharide), glycogen (branched animal storage), cellulose (linear beta-linked plant fiber), amylose (linear starch), glucose (monosaccharide).
• Examine options as potential row matches to diagram features (e.g., linear unbranched, branched, animal storage, disaccharide).
• Compare each option's sequence to standard features: cellulose (unbranched structural), amylopectin (branched), glycogen (branched storage), sucrose (disaccharide).
• Select option aligning all matches without mismatches.

Why B is correct:

• Cellulose is linear β-1,4-glucose (unbranched plant fiber), amylopectin has α-1,6 branches, glycogen is highly branched α-glucose for animal storage, sucrose is non-reducing glucose-fructose disaccharide—matching typical diagram features.

Why the others are wrong:

• A: Amylopectin isn't first (unbranched); sucrose doesn't fit storage.
• C: Glycogen isn't unbranched; amylose isn't typically last (branched storage).
• D: Glucose is monomer, not structural fiber like cellulose.

Final answer: B
