Q3. The term ‘ACE2’ is talked about in the context of
a) genes introduced in genetically modified plants
b) development of India’s own satellite navigation system
c) radio collars for wildlife tracking
d) spread of viral diseases
Answer: (d)
- Many different cell types have the protein known as ACE2 (angiotensin-converting enzyme). By breaking down the bigger protein angiotensinogen, it is an enzyme that produces smaller proteins that later control cellular processes. Before entering cells and infecting them, the SARS-CoV-2 virus attaches to ACE2 with the help of the spike-like protein on its surface. As a result, ACE2 serves as a receptor and cellular entry point for the virus that causes COVID-19. Many scientists are concentrating their efforts on a particular protein that the COVID-19 virus uses to infect human cells in their search for cures.
