Glucose molecules bond together in a process known as dehydration synthesis. what happens in this process? . water is used as a reactant in order to build the polysaccharide molecule.. a water molecule is formed from the hydrogen and oxygen atoms removed.. the reaction uses water molecules to break the bonds in each glucose.. water molecules are removed from each glucose molecule by the addition of heat. . is it the third one? @compassionate

A water molecule is formed from the hydrogen and oxygen atoms removed

Explanation:

When two glucose molecules join a water molecule is removed. The hydroxyl group (-OH) in one  glucose molecule combines with the H atom of the next glucose molecule. With the release of one molecule of water a covalent bond is formed that links two monomers of glucose. Gluocse is monomer or a monosacchardide. Two glucose molecules join together to form a dimer or a disaccharide called  maltose.

explanation:

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
