2019 Nobel Prize in Medicine/Physiology.

Britain’s Peter Ratcliffe, William Kaelin and Gregg Semenza of US shared the 2019 Nobel Medicine Prize for their work on how cells sense and adapt to oxygen availability.
The team revealed the understanding of how oxygen levels affect cellular metabolism.The trio will share prize money of 914,000 USD.
Oxygen levels vary in different parts of the body at different instances after a wound, while exercising or during a brisk walk. Based on the availability of oxygen, the metabolism of these cells differ. The cells produce new RBC or construct new blood vessels in a wound based on the oxygen levels.
