Question

The entire process of digestion is both ___ and ___.

• A. biochemical, biophysical
• B. mechanical, biophysical
• C. mechanical, biochemical
• D. electrochemical, biophysical

Answer 1

The correct option is C

mechanical, biochemical

The process of digestion is both mechanical as well as biochemical because the food is ground well and mixed with enzyme for better chemical action before it is pushed down the gullet. Once it reaches the abdomen the muscles of stomach start grinding the food one more time in between the layers of the stomach. This is then acted upon by various gastric juices which break down the substance into simpler chemical units.
