- Factors involved in the difference between oxyhemoglobin values and cyanmethemoglobin values in normal individuals.How a molecule of hemoglobin is able to bind oxygen efficiently in the lungs and yet release it efficiently in the tissues.Select all statements that correctly describe hemoglobin and myoglobin structure. Each hemoglobin molecule can bind four oxygen molecules; each myoglobin can bind one oxygen molecule. Molecular oxygen binds irreversibly to the Fe(II) atom in heme. Each iron atom can form six coordination bonds. One of these bonds is formed between iron and oxygen. Hemoglobin and myoglobin are heterotetramers. The heme prosthetic group is entirely buried within myoglobin. Both hemoglobin and myoglobin contain a prosthetic group called heme, which contains a central iron (Fe) atom. By itself, heme is not a good oxygen carrier. It must be part of a larger protein to prevent oxidation of the iron.

- Place a single word into each sentence to make it correct saturation The relationship between hemoglobin and Po2 is shown by an oxyhemoglobin dissociation curve. rises lowers At low Po2, the curve slowly load When the curve rises there is a rapid increase in oxygen loading. deficiency When the first heme group binds a molecule of oxygen, changes conformation to accept a second carbon dioxide Oxygen. Eventually at high Po2 levels, the hemoglobin approaches 100 % saturation and can not hemoglobin more oxygen.__________ is a substance secreted by cells in the lungs that reduces surface tension.True or False: Oxygen and carbon dioxide bind to different parts of hemoglobin.SEE MORE QUESTIONS
