Why is the beta-D-glucopyranose form of glucose more abundant than alpha-D-glucopyranose in aqueous solution?

4. a. In a procedure for testing blood glucose, a drop of blood is placed on a paper strip impregnated with the enzyme glucose oxidase and all the reagents necessary for the reaction.
The H2O2 produced causes a color change on the paper that indicates how much glucose is present. Since glucose oxidase is specific for the beta anomer of glucose and doesn’t act on alpha anomer, in spite of this specificity, the reaction is used in clinical assay for measuring total blood glucose which consists of a mixture of beta D glucose and alpha D glucose. Explain how this assay is effective in measuring total blood glucose?

Polymerase chain reaction (PCR) is a revolutionary method invented by Kary Mullis in the 1980s which copies the target sequence defined by a pair of primers exponentially. Can exponential amplification of any random sequence of DNA be achieved in PCR with only single primer? Hint: Refer the schematic in the diagram that represents randomly amplified polymorphic DNA (RAPD) marker technology. You can substantiate your answer with help of this diagram, if required.

One of the ingredients present in the venom of Indian spectacled cobra, Naja naja is phospholipase A2(PLA2). We have discussed the site of action of PLA2 in a glycerophospholipid. PLA2 from cobra venom thus degrades the glycerophospholipids present in the cell membrane leading to cell lysis releasing its cytoplasmic contents.
a. Explain taking an example of any glycerophospholipid present in the cell membranes, how action of PLA2 brings out lysis
