Q:

Gluconeogenesis is a term that describes the synthesis of

Answer

Gluconeogenesis is a metabolic pathway that leads to the synthesis of glucose from pyruvate and other non-carbohydrate precursors, even in non-photosynthetic organisms.


 


It occurs in all microorganisms, fungi, plants and animals, and the reactions are essentially the same, leading to the synthesis of one glucose molecule from two pyruvate molecules. Therefore, it is in essence glycolysis in reverse, which instead goes from glucose to pyruvate, and shares seven enzymes with it.

Q:

Would the following program compile?

main()

{

    int a = 10, *j;

    void *k;

    J = k = &a;

    J++;

    k++;

   printf ("\n%u %u", j, k);

}

Answer

An error would be reported in the statement k++ since arithmetic on void pointers is not permitted unless the void pointer is appropriately typecasted.

Q:

Refractive Index of glass with respect to water is

A) 4/3 B) 9/8
C) 2/3 D) 8/9
 
Answer & Explanation Answer: D) 8/9

Explanation:

Refractive Index of glass with respect to water can be calculated by 

(Refractive Index of glass with respect to air) × (1/Refractive Index of water with respect to air)

 

We know that,

Refractive Index of glass with respect to air = 4/3

Refractive index of water with respect to air = 3/2

 

Hence, Refractive Index of glass with respect to water = (4/3) x (2/3) = 8/9.
