Correct Answer : Option (D) - spread of viral diseases

Note :

Angiotensin-converting enzyme 2 (ACE2) is a protein on the surface of many cell types. It is an enzyme that generates small proteins – by cutting up the larger protein angiotensinogen –that then go on to regulate functions in the cell.

Using the spike-like protein on its surface, the SARS-CoV-2 virus binds to ACE2. Hence, ACE2 acts as a cellular doorway that is a receptor for the virus that causes COVID-19. The spike protein of SARS-CoV-2 can adopt at least 10 structural states in order to cling onto angiotensin-converting enzyme 2 (ACE2) receptor cells in humans.
