Expert Solution
Step 1Introduction
  • The given reaction is an example of oxidation and reduction reactions popularly called as redox reactions
  •  In redox reactions, there is a net gain or loss of electrons.
  • or there is gain or loss of hydrogen ions. 
  • In the given question it is clearly seen that disulfide linkage is formed by the removal of hydrogen atoms from bonded sulfur. Hence to carry out such reactions inside a living system there are electron carriers that are called NAD+ or NADP+.
  • This Nicotinamide dinucleotide (NAD) or nicotinamide dinucleotide phosphate (NADP) accepts electrons or hydride ions from the donor and itself reduced to NADH or NADPH forms. They act as coenzymes and facilitates various redox reactions inside cells.
