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. done starch 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 - molecule polysaccharide made of glucose units. Cells need small - molecule nutrients for energy production via cellular respiration. Starch molecules are too big to diffuse into cells, so they must be broken down into glucose. Also, glucose is the direct fuel for cellular respiration.

Answer:

Starch molecules are too large to diffuse into cells.
