Reika [66]

Answer:

Lysine 63.

Explanation:

The coenzyme may be defined as the non protein part of an enzyme that plays an important role in the enzyme functioning. Any cation or small molecule like amino acids can acts as coenzyme.

Lipoamide is important coenzyme that plays an important role in the metabolic pathways by undergoes the decarboxylation reactions. The reduced lipoamide known as dihydrolipoamide is used for the covalent attachment at Lysine 63 residues.

Thus, the correct answer is option (D).

1. to calculate molar mass , you need average atomic mass of each element.

formula is simple

suppose we have Na2CO3

here it says

there are

2 atoms of Na

1 atom of C

3 atom of O

now

molar mass = (total atoms of Na × average atomic mass of Na) + ( total atom of C × average atomic mass of C )+ (total atom of O × average atomic mass of O)

i hope you can figure out it now.

in case of (NH4)2

this means you have 2 count of NH4

so total atoms of N = 2

total atoms of H = 4×2 = 8

so on you can now figure it out

2. balanced equation

here LHS and RHS shoild have same number of atoms of each element .

for example

H2 + Cl2 => 2HCl

here 2 atoms of H combined with 2 atoms of Cl , we know H and Cl combined and formed HCl now because total H atoms are 2 and Cl atoms are 2 in LHS then we should also have 2 atoms of each in right side

so thats why we have 2HCl in right side.

Try to figure out . let me know if need any help
