(i) ${\mathrm{S}}_{\left(\mathrm{red}\right)}+{\mathrm{S}}_{\left(\mathrm{oxi}\right)}^1\to {\mathrm{S}}_{\left(\mathrm{oxi}\right)}+{\mathrm{S}}_{\left(\mathrm{red}\right)}^1\Rightarrow$ Transferase
(ii) $\mathrm{S}-\mathrm{G}+{\mathrm{S}}^1\to \mathrm{S}+{\mathrm{S}}^1-\mathrm{G}\Rightarrow$Hydrolases 
(iii) $\stackrel{X}{\stackrel{|}{C}}-\stackrel{Y}{\stackrel{|}{C}}\to X-Y+C=C\Rightarrow$Lyases 
(iv) Haem $\to$ Prosthetic group of catalase 
(v) Malate  $\to$ Competitive inhibitor of succinate dehydrogenase
