Physical and chemical change
A quick comic about how digestion contains two types of change-physical and chemical.
I heard you were learning about types of changes in science class today!
The process of digestion that took place after we ate contained physical change.
As your teeth chewed the pizza, it was physically broken into smaller pieces.
That is true! However, digestion also has chemical change.
Enzymes break large molecules into smaller ones in order to help the process continue! They may help break sugar molecules into individual starches.
These are representations of enzymes.
Huh. I never thought of it that way... Glad we could both get a better understanding of physical and chemical change!
