Carbon monoxide is a toxic gas that has a great affinity with haemoglobin and forms carboxyhemoglobin, hence reducing the oxygen-carrying capacity of haemoglobin.SummaryRespiration can be briefly described as an energy-releasing process involving the gaseous exchange. It is an essential life process th...
Human blood is red because its oxygen-binding protein, hemoglobin, contains iron. In addition to being blue, octopus blood is a poor carrier of oxygen, which helps explain the animal's sometimes apparent laziness. To cope with the low oxygen levels, the octopus maintains a constant high blood...
What is the effect of each of the following treatments on oxygen affinity of hemoglobin A in vitro? a. increase in pH from 7.2 to 7.4 b. increase in pCO2, from 10 to 40 tors c. increase in (BPG) from 2 x 10 to 8 x 10 4 M d, dissociation of alpha2beta2 ...
Due to its key role in mitochondria operation, regulation of respiration, ROS homeostasis, and yeast stress tolerance, VDAC was deemed as one of the key proteins responding to the alkaline pH. The VDAC porin closely interacts with the other proteins of known pore activity (F31207p, B10362p,...
Engineers have greatly improved technical features of MRI scanners, so it is common nowadays to see the blood vessels with amazing details within the brain, or visualize the beating heart or respiration. The brain is finally revealing its detailed anatomical structure with submillimetric reso- 20...
How do plants get oxygen for cellular respiration? How does hemoglobin transport oxygen? How many endothelial cells are present in the cornea? How are oxygen and carbon dioxide transported in the blood? How does oxygen get into the body tissues and carbon dioxide is removed? How do red blood...
Anemia arises during a wide variety of pathological conditions including RBC intrinsic disorders, hemoglobin alterations, malnutrition, chronic inflammation, chronic kidney disease and cancer (reviewed in Sankaran and Weiss, 2015). The HIF pathway is a profound regulator of erythropoiesis through its ...
Stress is regulated by theautonomic nervous system. This is a part of the nervous system that oversees involuntary functions like heart rate, respiration, blood pressure, and digestion. During moments of extreme stress, it also triggers the "fight-or-flight" response.1 ...
Explain the mechanics of respiration. Begin with inhalation. Considering Type 1 Alveolar cell. How respiratory gases move in and out of this type of cell? Why is the movement of gases is important to respiratory physiology? Describe the role of hemoglobi...
Explain what happens to the CO_2 that moves out of the tissues into the blood in internal respiration: How is CO_2 transported? What is the effect of increased CO_2 on the pH in tissues? How do changes in pH affect the affinity of hemo...
