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.

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.

Starch molecules are too large to diffuse into cells.

Explanation:

As mentioned "Starch molecules are actually long chains of glucose molecules"

Thus they are broken down to glucose To make their transport (by diffusion) easier.
