Answer:
d) A constitutively active mutant form of PKA in skeletal muscle cells would lead to an excess in the amount of glycogen available.
Explanation:
This occurs in the process of Glycogenolysis. The process involves breaking down of glycogen to glucose -1- phosphate and glycogen which helps in the release of glucose into the blood stream to prevent hypoglycemia(low blood sugar). The glucose-1-phosphate is later converted to glucose -6-phosphate. The latter enters the glycolytic pathway in which the reaction is catalysed by the enzyme phosphoglucomutase.
This homeostatic glucose regulation is regulated by the protein kinase(PKA)/ cAMP pathway in the skeletal muscles, the liver and the pancreas.
Precipitation differences are the factor that does not contribute to "water stress" on the Earth.
<u>Explanation:</u>
- Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
- Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
- An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.
