AA phosphate group is released as a byproduct
BA hydrogen ion is taken in from the surroundings
CA water molecule is released as a byproduct
DA water molecule is taken in from the surroundings
Answer & Solution
Correct answer: C. A water molecule is released as a byproduct
1. Monomers combine using covalent bonds to form larger polymers.
2. As each bond forms, the monomers release a water molecule as a byproduct.
3. The name dehydration synthesis records exactly this, putting units together while losing water.
4. Taking water in is the opposite reaction, hydrolysis, so the two options about taking water or hydrogen in are wrong.
