Question 16

If 3 glucose molecules are linked to make a carbohydrate, what happened with water?

Answer 16

2 water molecules were produced

Question 17

If a protein is digested into 5 amino acids, what happened with water?

Answer 17

4 water molecules were used up.

Question 18

Why is water a basic feature of life?

Answer 18

It is essential to our chemistry: we can’t build molecules or break them without using water molecules.
