<span>Oxygen carried in a hemoglobin molecule is bound to an iron atom.
</span>The red blood cells contain a pigment called hemoglobin, each molecule of which binds four oxygen molecules.
This protein carries oxygen to the cells and carbon dioxide to the lungs.
It is the iron atom<span> that binds </span>oxygen<span> as the blood travels between the lungs and the tissues.</span>
The 10<span>% </span>Rule<span> means that when </span>energy<span> is passed in an ecosystem from one trophic level to the next, only ten percent of the </span>energy<span> will be passed on. An </span>energy pyramid<span> shows the feeding levels of organisms in an ecosystem and gives a visual representation of </span>energy loss<span> at each level.</span>
The answer is 4 atoms exist in the products of this reaction.(that's what I got)
Answer: Arginine is an amino acid that is incorporated into proteins. So if cells can not make or obtain arginine, the cell can not make proteins needed for survival.
Explanation:
Arginine is an amino acid used to build proteins, and it is classified as a semiessential or conditionally essential amino acid.
Proteins are large molecules consisting of long chains of amino acids. They perform many functions such as catalysing metabolic reactions, providing structure to cells and organisms, and transporting molecules, among many others.
Most notably, arginine is part of proteins that play an important role in many different processes such as cell division, immune function, wound healing and the release of hormones. <u>Without this amino acid, the cell cannot manufacture the proteins necessary for proper functioning</u>. So the cell dies because it cannot function properly.
