Is digesting food a chemical change?

Digestion of food is an example of chemical change. Digestion is considered as chemical change because enzymes in the stomach and intestines break down large macro-molecules into simpler molecules so that the body can absorb the food easily.

Is making French fries a chemical change?

When cooked at high temperatures, sugars react with amino acids, including asparagine, in a chemical process known as the Maillard reaction. The reaction is what gives fried potatoes their prized flavor and color, but it is also what produces acrylamide.

Is the process of digestion a physical or chemical change?

Digestion is considered a physical and chemical change because enzymes in the stomach and intestines break down large macromolecules into simpler molecules so that the body can more easily absorb the food.
