What will happen if our bloods 'Fe' or iron molecule is exchanged with 'Cu' or copper? Our RBC or red blood cell have a protein called hemoglobin, which have a iron molecule inside of them. This iron helps in carrying our oxygen and carbon dioxide. Now if we exchange the iron molecule with copper It'll turn BLUE. That's they called blue blood🤣. This compound is called 'hemocyanin' other than 'hemoglobin '. I always encourage to do extra research before believing anything. Happy reading.
