I’m not sure of your question but a lobectomy is an surgical removal of a lobe of the lung. This is done to remove a part of the diseased lung.
Answer:
C) substitutions that reduce the affinity of hemoglobin for oxygen
Explanation:
Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.
The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.
Answer:
Is characteristic of Diabetes.
Explanation:
Diabetes is a disorder in which blood sugar increases due to the fact that there is mechanism by which sugar enters the cell is somehow affected.
There are different types of this disorder, the most common ones are the following,
1. Diabetes type 1, is an autoimmune disorder in which the cells that are in charge of producing insulin are destroyed, as a consequence there is not enough insulin (responsible for allowing the glucose channels to open and transport glucose into the cell). Therefore, sugar remains in blood circulation. When glucose levels are too high, it starts filtering through the kidneys and ends up in the urine.
2. Diabetes type 2, is triggered by different factors, there are genetic and environmental factors that trigger this disease. In this case, cells are 'resistant' to the insulin effect, so the body reacts by secreting more insulin. As a consequence, cells in charge of secreting insulin are overworked and at the same time, the body cells keep on increasing the resistance to insulin. There is a point in which this compensation fails to work, and blood sugar rises. When the levels become high, glucose starts filtering through the kidneys and ends up in the urine.
There are more types of diabetes, such as gestational diabetes or LADA. In this cases the cause of the disease varies, but the outcome is the same, increased blood glucose levels and presence of glucose in the urine.
