Question

based on what you learned in the lab, why does your body need to break down starch into glucose?○ starch contains more energy than glucose.○ starch molecules are too large to diffuse into cells.○ glucose molecules are larger than starch molecules.donestarch molecules are actually long chains of glucose molecules. when you eat food containing starches, such as potatoes, your body breaks down the starch into the glucose molecules. your cells then use glucose to obtain energy through cellular respiration.

Explanation:

Starch is a large polysaccharide made of glucose chains. Cells can only take in small molecules via diffusion or transport; large starch molecules cannot cross cell membranes. Breaking starch into glucose allows cells to absorb and use it for cellular respiration energy. The other options are incorrect: starch does not have more energy per unit than glucose, and glucose is smaller than starch.

Answer:

Starch molecules are too large to diffuse into cells.
