ARedoxreaction is a reaction in which thetransferof electrons occurs between two or moremoleculesor compounds. An ion, atom or molecule cangainorlosean electron.The correctansweris:Optionb. formation of free electronsThis can beexplainedas:Electrons can berepositionedfrom one molecule to another with the help ofhydrogenatoms or hydride ions.When electrons transfer from one molecule itreducesandoxidizesmolecules but are not releasedfreelyin the system.H+ can betransferredfrom molecules like in the case ofNADandNADP.Free H+ is alsoproducedduring the redox of nicotinamide enzyme reactions. They are released to generateATP.Therefore,freeelectrons are not formed inbiologicalredox.To learn more aboutoxidation-reduction reactionsfollow the link:brainly.com/question/4222605...
