When comparing proteins and polysaccharides, the following similarities
lianna [129]

Answer:

The comparison of proteins and polysaccharides establishes that they have similarity in both consist of linked monomers via the process dehydration reactions.

Explanation:

Both proteins and polysaccharides are polymers whose structure consists of the union of monomers. In the case of proteins the monomer is the amino acid, while in the polysaccharides can be glucose molecules.

The process of polymer formation is called polymerization, and one of the reactions that this process allows is <u>polycondensation</u>, where a water molecule is lost in the union of monomers.

The loss of water in a chemical reaction involves dehydration, a characteristic shared by the processes of adding monomers to proteins and polysaccharides.

The other options are not correct, because

  • <em>Hydrolysis produces the rupture of molecules, with the intervention of water.</em>
  • <em>Only polysaccharides are sugars bound by the dehydration synthesis process.</em>
  • <em>Only proteins consist of amino acids linked through the process of hydrolysis.</em>
