Question

Explain the physical and chemical changes that occur from when you eat food until it is digested.

Answer 1

Physical change - Macro-molecules splits into smaller particles, and so their size would reduce

Chemical change - They splits into their monomers, like Proteins convert into amino acids, fats into glycerol and fatty acids etc

Hope this helps!

Answer 2

the physical changes are you are breaking down the food u eat and the chemical changes are when the enzymes in your stomach break down the food that you have already eaten
