Question

assignment: reflect on the lab active
apply diffusion principles to a real - world
scenario
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

Explanation:

Starch is a polysaccharide (long - chain carbohydrate), and glucose is a monosaccharide. Cells have semi - permeable membranes. Smaller molecules like glucose can pass through the cell membrane via diffusion (or other transport mechanisms), while large starch molecules cannot. Energy content: Glucose is the immediate energy source, and starch is a storage form. When broken down, the total energy from starch (as it's made of glucose units) is similar to the sum of its glucose components. Also, glucose molecules are smaller than starch molecules.

Answer:

Starch molecules are too large to diffuse into cells.
