Shared structural features of amylose and cellulose

Steps:

• Identify amylose as a linear glucose polymer with α-1,4 linkages and cellulose as a linear glucose polymer with β-1,4 linkages.
• Recall that both are polysaccharides composed of glucose monomers.
• Determine which statements apply: statement 1 (linear structure), statement 2 (glucose-based), but not statement 3 (e.g., branched or different linkage).
• Select option matching statements 1 and 2.

Why B is correct:

• Amylose and cellulose share linear chains of glucose units, aligning with definitions of unbranched polysaccharides.

Why the others are wrong:

• A includes 3, which likely describes branching or α-linkages not true for cellulose.
• C omits 2, ignoring their common glucose composition.
• D includes 3 but excludes 1, missing the linear feature.

Not enough information on exact statements 1-3 to confirm fully.

Final answer: B
