Food is Digested So That

Question

Food is digested so that
A)it can be swallowed.
B)it can be converted to waste.
C)nutrients are small enough to enter the cell.
D)All apply.

Accepted Answer

Food is digested so that the nutrients can be broken down into small enough molecules to pass through the cell membrane and enter the cells, where they can be utilized for energy and other cellular processes. The other choices are not entirely accurate; food is swallowed so that it can enter the digestive system, and waste is a byproduct of the digestive process, but not the main reason for it.
