Question

In living systems, water is involved as a chemical in

• A. Photosynthesis and respiration
• B. Synthesis of polymers
• C. Hydrolysis of biochemicals
• D. All of the above

Answer 1

The correct option is D All of the above

Photosynthesis and respiration is an enzymatic reaction where the water acts as an electron donor to PS II. The polymers are the macromolecules that are synthesised by the addition of monomers. Synthesis of biomolecule is also a polymerization reaction where water is used as a proton donor for covalent bond formation. Hydrolysis of biochemicals also require water for breakdown of various bond between the molecules to convert them into simpler form. Thus, the correct answer is option D.
