Answer:
Histidine
Explanation:
A heme group is a prosthetic group composed of a protoporphyrin ring and an iron (Fe) atom that binds to oxygen (O2) in hemoglobin and myoglobin. Hemoglobin (Hb) is a protein in red blood cells (erythrocytes) that carries oxygen from the lungs to the tissues, which is composed of four polypeptide chains, each with a heme group. Moreover, myoglobin is a monomeric protein located mainly in the muscles, which contains one heme group, being thus similar to hemoglobin monomers. The proximal and distal are evolutionarily conserved amino acid (histidine) residues whose names (proximal and distal) refer to their position with the iron (Fe) atom in the heme group. The proximal histidine connects the heme group with the proteins (either in monomeric myoglobin or in one subunit of Hb), whereas distal histidine contributes to stabilize these proteins while carrying O2.

emotional comfort. according to some studies in psychological science, chicken soup is good for your emotions. the soup plays a great role in reducing the irritation that accompanies common cold. it emotionally and psychologically makes an individual to feel better. in fact individuals are encourage to over eat chicken noodle in the duration they suffer from the common cold.
Answer:
The answer here would be D, proteins.
Explanation:
Transcription forms RNA, while translation forms a polypeptide amino acid chain. Through a long process the polypeptide amino acid chain will eventually synthesize a protein.
