Solution
The correct option is B Water Condensation reaction joins two molecules by releasing a molecule of water. This reaction is responsible for joining of monomer units to form a polymeric biomolecule or biomacromolecules.
ATP is the energy currency of the cell and is used and replenished continuously during metabolic reactions. Hydrogen is released during dehydrogenation reactions. NAD+is reduced to NADH during some reactions. NADH is one of the high energy chemical intermediates i.e form in which energy is stored in our body.
