Describe the properties of haemoglobin that enable it to carry out its function of oxygen and carbon dioxide transport
Step by step
Solved in 2 steps
- contrast the characteristics and function of myoglobin versus hemoglobin.Describe how the cooperative binding of hemoglobin allows for optimal oxygen delivery.Which of the following statements regarding the transport of oxygen by hemoglobin is correct? Upon binding of oxygen to heme, a shift in the position of the distal His ultimately induces the switch from T to R states When fully bound to oxygen, AG(R-state)Describe how hemoglobin functions in the transport ofboth oxygen and carbon dioxide.The ability of hemoglobin to bind oxygen decreases with decreasing oxygen concentration and also decreases with increasing carbon dioxide concentration. What effect do these phenomena have on the delivery of oxygen to tissues?Explain how biphosphoglycerate helps in the delivery of oxygen to the tissues by hemoglobin through cooperative binding.Which of the following situation would you expect in a patient with a type 2 cells dysfunction? The ciliated epithelium of the trachea would lack its normal watery layer. The resistance in the conducting airways would increase. Some alveoli may collapse and prevent ventilation in that part of the lungs. The lungs would become too easily stretched out. The expiratory reserve volume would shrink. Please consider providing detailed explanations of both correct and incorrect options.Which of the following statements about oxygen transport is TRUE. Increases in temperature and decreases in pH cause myoglobin to release oxygen to improve delivery to the hemoglobin in muscles. A molecule of myoglobin has higher oxygen binding capacity than a molecule of hemoglobin. Myoglobin has a higher oxygen affinity than does hemoglobin. Fetal hemoglobin has a lower affinity for oxygen than maternal hemoglobin, which makes it better suited to extract oxygen from the maternal circulation.The diffusion coefficient of a gas is a constant and is not affected by disease states or treatment options. In contrast the other factors that determine gas diffusion through the respiratory membrane is affected by changes.Name the factors that can cause an increase in the diffusion rate through the respiratory membrane and provide detailed examples of conditions that will cause this increase.SEE MORE QUESTIONS
