Answer:
b). False.
Explanation:
Synergistic effect represents interaction between two or more substances or factors to generate a combined effect higher than the sum of their effects when they function separately.
Cortisol is a hyperglycemic hormone that increases level of glucose in blood. It is secreted by adrenal gland during stress conditions, which increases level of blood sugar by producing of glucose from liver.
On the other hand, insulin is a hypoglycemic hormone that reduces level of glucose in blood. It is secreted by pancreas when blood sugar level becomes too high and decreases blood sugar level by promoting storage of glucose for future use.
As cortisol and insulin show opposite effects, they cannot be considered as synergistic in their actions.
Thus, the given statement is false.
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.
If they understand how they work, it helps them with create new vaccines, medicines, etc.
