Digestion

Definition:

The process by which food or feed is prepared for absorption



It involves the breakdown of large molecules (
polymers
) to
smaller molecules (
monomers
) by

mechanical
,
enzymatic
,
chemical
, and(or)
microbial

actions

Results:

1)
A decrease in molecular size

2)
An increase in solubility

3)
The monomers can be absorbed & utilized by different cells
