Question
Chapter 26.1, Problem 2WDYL
Summary Introduction
To analyze:
The primary difference between mechanical and chemical digestion.
Introduction:
Digestion is a type of catabolic process. This is because digestion involves the breakdown of complex ingested food substances into simpler units. This makes those food units easily accessible by the blood which then carries these units to various organs for utilization.
