Question

1. to get back to the original monosaccharides, you would have to reverse the process of dehydration synthesis. you would need to replace the oh- and the h+ groups. what molecule did you have to split apart to give the oh- and the h+ groups?

Explanation:

Dehydration synthesis removes a water molecule ($H_2O$) to link monomers. Reversing this (hydrolysis) splits water into $H^+$ and $OH^-$ to restore the original monosaccharides.

Answer:

Water ($H_2O$)
