Water that is referred to as preformed water includes what?

Question

I have been asked a question in Anatomy & Physiology and I can't find ANYTHING on the make-up of preformed water.

The question asked is....

Water that is referred to as preformed water includes what?

a. ingested food

b. beverages

c. dehydration synthesis and metabolism

d. both a & b

e. both a & c

This is a question on our final. Our teacher gave it to us beforehand because he did not lecture on it.

Any help, including the definition of preformed water, would be greatly appreciated.

Answer 1

The kind of water found within food

Eg.: A peach has a lot of preformed water.

So answer = "a".
