The term ‘ACE2’ is talked about in the context of
- genes introduced in the genetically modified plants
- development of India’s own satellite navigation system
- radio collars for wildlife tracking
- spread of viral diseases
Explanation
Option (d) is correct
- The term ‘ACE2‘ is primarily discussed in the context of the spread of viral diseases. ACE2 stands for Angiotensin-Converting Enzyme 2, which is a protein found on the surface of cells in various organs, including the lungs and respiratory tract. 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 – like a key being inserted into a lock – prior to entry and infection of cells. Hence, ACE2 acts as a cellular doorway – a receptor – for the virus that causes COVID-19.
