Question

Food molecules such as proteins cannot be absorbed unless they are digested.
Give one reason why.

Answer 1

Answer:

Your body can't absorb proteins in their natural state. Certain proteases in your stomach and pancreas break the bonds that hold the amino acids in protein together so your body can absorb the composite amino acids individually.

Answer 2

Food molecules cannot be absorbed unless digested because ; They are too big to pass through the plasma membrane, in their natural state.

The food molecules such as protein needs to be broken down into its composites amino acids for easy absorption. food molecules, cannot be absorbed in their natural state because they are too big to pass through the plasma membrane.

Protein is broken down ( digested ) by proteases and pancreas into composite amino acids that is absorbable into the human cells.

Hence we can conclude that protein cannot be absorbed unless digested because they are too big to pass through the plasma membrane, in their natural state.
