Which of the following is not true of chemical digestion?
a. it consists of a series of catabolic reactions
b. it uses a variety of enzymes
c. it includes chewing
d. it breaks complex molecules down to smaller molecules that can be absorbed

The correct option is : c. it includes chewing

Explanation:

Digestion is a process which involves the breakdown of the large insoluble food molecules into small and simple molecules. Digestion is divided into two types: Mechanical and Chemical Digestion.

The mechanical digestion of food involves physical breakdown of large food particles into the smaller ones. Example : mastication or chewing

Whereas, chemical digestion is the breakdown of complex molecules of food to simpler molecules, which can be absorbed easily. This process involves series of ezyme-catalyzed catabolic reactions.

Therefore, chemical digestion does not involve chewing.
