Given, Molecular weight of the Protein X, m = 15,000
Da = 15,000 g/mol = 15 mg/mol
Weight of the Protein in solution, W = 100 mg
Volume of the solution, V = 100 mL
Therefore, molarity of the solution = (W/m) × (1000/V) M
= (100/15) × (1000/100)
= 66.67 M

Correct Option: A

Da = 15,000 g/mol = 15 mg/mol
Weight of the Protein in solution, W = 100 mg
Volume of the solution, V = 100 mL
Therefore, molarity of the solution = (W/m) × (1000/V) M
= (100/15) × (1000/100)
= 66.67 M

Number of moles present in the solution of protein = (100/15) = 6.667 moles
Number of molecules present in the solution = no. of moles × Avogadro’s number
= 6.667 × 6.022 × 10²²  
= 40.146 × 10²² molecules

Correct Option: E

Lactate dehydrogenase (NAD+ oxidoreductase) is a ubiquitous enzyme among vertebrates and carries out the reaction: NAD+ + lactate <=> NADH + Pyruvate. Glycogen Phosphorylase catalyzes phosphorolytic cleavage of α (1, 4) glycosidic linkages of glycogen, releasing glucose-1-phosphate as the reaction product. Pyridoxal phosphate (PLP), a derivative of vitamin B6, serves as prosthetic group for Glycogen Phosphorylase. Nitrogenase is a two-protein complex. One component, called Nitrogenase Reductase (NR) is an iron-containing protein that accepts accepts electrons from ferredoxin, a strong reductant, and then delivers them to the other component, called Nitrogenase, or Iron-Molybdenum protein. There are several proteins in mammalian cells that can metabolize hydrogen peroxide and lipid hydroperoxides. These proteins include four selenium-containing glutathione peroxidases that are found in different cell fractions and tissues of the body. These proteins are called glutathione peroxidases.

The Clark electrode is an electrode that measures oxygen on a catalytic platinum surface using the net reaction:
O₂ + 4e^– + 2H₂O → 4OH^–
These are also known as dissolved oxygen electrodes.
Redox probe also known as a pH probe is used for the measurement of pH.
A load cell is a transducer that is used to create an electrical signal whose magnitude is directly proportional to the force being measured. It can be used to measure the liquid levels. To measure level, the load cell must be incorporated into the vessel's support structure.
The Diaphragm Pressure Gage uses the elastic deformation of a diaphragm (i.e. membrane) instead of a liquid level to measure the difference between an unknown pressure and a reference pressure.
