A. to push each other away
Answer : Option B) Glycerol because it is more viscous and has a larger molar mass.
Explanation : Viscosity is a quantity which is expressed in terms of the magnitude of internal friction in a fluid, as measured by the force acting per unit area resisting uniform flow. In simple words, due to high intermolecular forces of attraction the viscosity is increased, as there will be more resistance between the molecules for flowing.
Usually high molecular compounds have high viscosity. In this question, glycerol has high molecular weight along with high intermolecular forces of attraction between the molecules as compared to water and therefore, has high viscosity.
Answer: An insulator would be made out of material unable to conduct electricity due to lack of fluid movement for electrons, such as rubber. Rubber properties not only prevents them from freely moving, but also helps electrons stay tightly bound to each other.
Hope this helps ^_^
Answer:
The correct option is B
b. Phosphorylation by a kinase using ATP (which turns the complex off) and dephosphorylation by a phosphatase (which turns the complex on).
Explanation:
The pyruvate dehydrogenase complex is described as a complex having many enzymes that catalyse decarboxylation of pyruvate by oxidation to yield NADH and acetyl‐CoA, which makes the influx of acetyl-coA from glycolysis to increase into the Krebs cycle.
It can be found in the mitochondrial matrix and pyruvate which is conveyed through enzyme Pyruvate Translocase to PDH complex.
Regulation of pyruvate dehydrogenase complex occured through allosteric effectors as well as phosphorylation.the main regulatory processes controlling pyruvate dehydrogenase's activity in eukaryotes such as plants and animals Phosphorylation is by a kinase using ATP which first turns the complex off and the later dephosphorylation by a phosphatase which turns the complex on
