The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment of the outer; as the protons flow back to the inner compartment, the energy of their movement is used to add phosphate to ADP, forming ATP.

A uniform rod of length 200 cm and mass 500 g is balanced on a wedge placed at 40 cm mark. A mass of 2 kg is suspended from the rod at 20 cm and another unknown mass 'm' is suspended from the rod at 160 cm mark as shown in the figure. Find the value of 'm' such that the rod is in equilibrium. 

(g = 10 m/s²)

The unit of length convenient on the atomic scale is known as an angstrom and is denoted by A : 1 A = 10⁻¹⁰m. The size of a hydrogen atom is about 0.5Å. What is the total atomic volume in m³ of a mole of hydrogen atoms?

The relation between internal energy U, pressure P and volume V of gas in an adiabatic process is U = a + bPV,  where a and b are constants. What is the effective value of adiabatic constant γ ?
