GPT-5 mini · Answer

Starch molecules are too large to diffuse into cells.

Starch is a polysaccharide (many glucose units bonded together) and cannot cross cell membranes. Digestive enzymes (e.g., amylase) break it into glucose monomers, which are small enough to be absorbed by the intestines and taken into cells for cellular respiration (ATP production). The other statements are incorrect: glucose is smaller than starch, and the need to break starch down is about size/absorption, not that starch somehow has “more usable” energy per se.
