Dehydration synthesis links two monomers by
A.removing a water molecule as a bond forms
B.adding a water molecule to split a bond
C.transferring electrons to form ions
D.forming hydrogen bonds between monomers
Explanation
Core Concept
In a condensation or dehydration reaction, formation of a covalent linkage is accompanied by net loss of water. This is a useful model for forming many glycosidic bonds and for comparing polymer-building with hydrolysis. It should not be described as the universal mechanism by which 'all four macromolecule classes polymerize': lipids are not true polymers, and cells build proteins and nucleic acids through more specific activated, enzyme-catalyzed mechanisms.
Correct Answer
Aremoving a water molecule as a bond forms
