The unusual property that cytochromes have in common with hemoglobin or myoglobin is that all of them contain heme groups. Cytochromes are heme-containing electron transport enzymes which are essential for the oxidative metabolism necessary to generate adenosine triphosphateas well as for the oxidative degradation of drugs and endogenous substrates. 
        
             
        
        
        
<span>Viruses are regarded as being on the borderline of living and non-living because it exhibits characteristics of both living and non-living organisms. Inside a host, the virus can act as a living organism using the host's cellular system while outside the host, the virus crystallizes that makes them incapable of conducting metabolic activities. </span>
