Chemistry

Isoenzymes are the different enzymes that catalyse the same biochemical reaction. However, they differ in amino acid composition and kinetic properties. Examples of isoenzymes are hexokinase and lactate dehydrogenase. 

Number of mole of $\mathrm{X}=\frac{6.022*{10}^{22}}{6.022*{10}^{23}}=\frac{10}{\text{Molar mass of}\mathrm{X}}$

So molar mass of $X=100\mathrm{g}$

Molarity $=\frac{5}{100*2}=0.025\mathrm{M}$

Ans. $=0.025\mathrm{M}$

$\mathrm{M}=25*{10}^{-3}$

So $P=25$

According to Faraday law

  $\mathrm{W}=\mathrm{Z}\mathrm{I}\mathrm{t}*\eta \mathrm{}$ Where $\eta =$ efficiency

or $W=\frac{E}{96500}*1*t*\eta$

Putting values

$.104=\frac{(52/3)*2*8*60*\eta }{96500}\Rightarrow \eta =0.6$

So percentage efficiency $=60\mathrm{\%}$

For isotonic solution

${\mathrm{i}}_1{\mathrm{C}}_1={\mathrm{i}}_2{\mathrm{C}}_2\mathrm{}$ ffor protein $\left.\mathrm{i}=1\right\}$

${\mathrm{C}}_1={\mathrm{C}}_2$

$\frac{0.73*1000}{M_A*250}=\frac{1.65}{M_B*1}$

$\frac{{\mathrm{M}}_{\mathrm{A}}}{{\mathrm{M}}_{\mathrm{B}}}=\frac{0.73*4}{1.65}=1.77=177*{10}^{-2}$

Asp - Glu - Lys pripeptide is:

No. of $\mathrm{C}\mathrm{O}$ group $=5$

Phosphinic acid is hypo phosphorous acid $\left({\mathrm{H}}_3{\mathrm{P}\mathrm{O}}_2\right)$ .

$\mathrm{N}\mathrm{a}\mathrm{O}\mathrm{H}+{\mathrm{H}}_3{\mathrm{P}\mathrm{O}}_2?{\mathrm{N}\mathrm{a}\mathrm{H}}_2{\mathrm{P}\mathrm{O}}_2+{\mathrm{H}}_2\mathrm{O}$

For neutrization

${\left({\mathrm{N}}_1{\mathrm{V}}_1\right)}_{\text{acid}}={\left({\mathrm{N}}_2{\mathrm{V}}_2\right)}_{\text{base}}$

$0.1*10=0.1*{\left({\mathrm{V}}_{\mathrm{m}\mathrm{L}}\right)}_{\mathrm{N}\mathrm{a}\mathrm{O}\mathrm{H}}$
