What type of blood cell contains hemoglobin and carries oxygen? What is the other name for the red blood cells? What are the main major types of blood substitutes, and when would one be used over the other? What are the different blood types and what's the difference?
Discuss the role of hemoglobin in the transport of O_2 and CO_2. What factors affect the affinity of hemoglobin for O_2? A molecule of hemoglobin that is 100% saturated would have oxygen molecules. Which oxygen-carrying pigment would you expect to have the lowest affin...
Oxygen-Rich Blood: Oxygen-rich blood is the supply of blood in the body that has been oxygenated in the lungs. Through gas exchange in the alveoli of the lungs, oxygen molecules come in contact with the red blood cells and bond to the hemoglobin on those cells. ...
How many oxygen molecules are bound when a hemoglobin molecule is 75% saturated? What is a hematocrit measuring? A) the amount of hemoglobin in blood B) the percentage of blood that is comprised of red blood cells only C) the percentage of b...
Naïve T cells will circulate through the blood and lymphatic system until becoming activated by encountering an APC with a corresponding antigen. Antigens play a significant role in T cell activation and can initiate a full-scale immune response. Many naïve T cells will remain in the blood...
While the study participants focused on their work, Wiehler and his team scanned the glutamate (谷氨酸) in the brains of the participants. Glutamate is an important signalling molecule in the brain that works in memory and learning. Too much glutamate may upset the brain’s functions, which mea...
In recent years, anti-tumor pharmacodynamics studies have found that one of its active ingredients, the small molecule compound of rhodopsin, has a relatively strong anti-cancer effect. In vitro and in vivo anti-tumor studies have found that the compound can improve tumor treatment effects and im...
Both adrenaline and cortisol are made in your adrenal glands and released into your blood when you have a stressful experience. But your body releases these different hormones at different times. Your body releases adrenaline at the beginning of your stress response, and it's main effect is to...
Hemoglobin is made of 1 globin molecule that is comprised of how many protein chains? Which one of the blood cells is a phagocyte? What plasma proteins are involved in clotting and which aren't made by the liver? Which of the following is the storage protein for oxygen found in skeletal ...
What molecule does aerobic respiration use that anaerobic respiration is missing? (a) oxygen (b) glucose (c) exercise (d) light Cellular Respiration: Cellular respiration is the process by which energy (in the form of ATP) is generated inside cel...
