Nitrogen gas is nearly an inert gas.
Hemoglobin is optimized for bonding with oxygen, but bonds even better to carbon monoxide (which makes carbon monoxide such an effective poison).
All of the elements in hemoglobin are inorganic. The important element is iron, which allows hemoglobin to carry oxygen (and carbon dioxide).The elements present in hemoglobin are iron, sulfur, nitrogen, carbon, hydrogen, and oxygen.
about 70 percent of the atmosphere is nitrogen
20.5 % ~ 21 %
Nearly all of the nitrogen in a diet is present as amino acids in proteins. The average nitrogen content of proteins was found to be around 16 percent.
Nitrogen has been present forever. It is the most abundant gas. Industrial revolution has changed it's concentration.
78 percentage of nitrogen.21 percentage of oxygen.1 percentage of other gases. Example-argon,carbon dioxide,helium,neon & methane. -superman
Hemoglobin is present in red blood cells.
the answer is hemoglobin.
78% nitrogen, 21% oxygen, 1% water vapor, and i forget the rest
Hemoglobin present while chlorophyll absent .
iron
about 70 percent of the atmosphere is nitrogen
