NEET BIOLOGY

Detailed explanation-1: -The monomers combine with each other using covalent bonds to form larger molecules known as polymers. In doing so, monomers release water molecules as byproducts. This type of reaction is known as dehydration synthesis, which means “to put together while losing water.”

Detailed explanation-2: -Assorted combinations of heat, pressure and catalysis alter the chemical bonds that hold monomers together, causing them to bond with one another. Most often, they do so in a linear fashion, creating chains of monomers called polymers.

Detailed explanation-3: -3.1 Polymer Structure. Polymers are held together by primary bonds (covalent bonds) and secondary bonds (van der Waals and hydrogen bonds). In covalent bonding there is a sharing of valence electrons (the s and p shells) to complete an octet (a group of eight electrons) around atoms.

Detailed explanation-4: -In a protein, amino acid monomers are held together by covalent peptide bonds between the amino group of one monomer and the carboxylic acid group of the adjacent monomer.

Detailed explanation-5: -Peptide bonds link monomers in a polymer. It is formed out of dehydration, that is, the amino group and carboxyl group of two different amino acids react to give rise to peptide bonds.
