WebCorrect option is A) Hb contains a protein portion called globin and a pigment portion called haem. The haem portion consists of four atoms of iron, each capable of combining with a molecule of O 2. Thus, one Hb carries 4 molecules of O 2. Was this answer helpful? WebOct 22, 2024 · 1. Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen. 2.By itself heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron atom. 3.Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind only one oxygen molecule. 4.
WebJul 18, 2024 · Myoglobin is a protein located primarily in the striated muscles of vertebrates. MB is the gene encoding myoglobin in humans. It encodes a single polypeptide chain with one oxygen binding site. … WebHemoglobin vs. Myoglobin: Hemoglobin refers to a tetramer oxygen transport protein that can bind with four oxygen atoms and is found in red blood cells. On the other hand, myoglobin is a monomeric protein that has lower binding capacity than hemoglobin and is often found in muscle tissue, serving as the intracellular storage for oxygen molecules.
WebOxygen solubility in aqueous solution is low. <10-4 M, an insufficient concentration for metabolic needs. The blood of organisms contains hemoglobin (150 g/L) which can carry oxygen concentrations of 0.01 M which is the same oxygen concentration as the air in our atmosphere. I.
