The phosphorylation of adp3− is given by: adp3−+h++hpo2−4→atp4−+h2o(l) . at t=310k the molar gibbs energy change for the phosphorylation of adp is δgrxn=32.0kj/mol . in the cell the phosphorylation of adp3− is coupled to the oxidation of glucose by the reaction c6h12o6+38adp3−+38h++38hpo2−4+6o2→3 8atp4−+44h2o+6co2. we define the efficiency of this coupling as the fraction of the molar gibbs energy change from oxidation of glucose that is diverted into adp phosphorylation. calculate the efficiency ϵ of this coupling.

a mercury barometer is a device that uses the physical properties of mercury in a tube to measure barometric pressure. mercury barometers are used for : -

1. measurement of atmospheric pressure  

2. determining the altitude of a place

3. weather forecasting

4. calibration and checking of aneroid barometers

5. application in fluid mechanics

6. measurement of pressure in aircrafts

7. surface weather analysis

8. preparation of barographs

9. usage in physical sciences like physics, astronomy & chemistry

10. preparation of aircraft altimeters

characteristics of mercury barometer : -

1.used to define and measure atmospheric pressure.

2.on the average at sea level the column of mercury rises to a height of about 760 mm.

3.this quantity is equal to 1 atmosphere.

4.it is also known as standard atmospheric pressure.

5.a barometer in which the weight of a column of mercury in a glass tube with a sealed top is balanced against that of the atmosphere pressing on an exposed cistern of mercury at the base of the mercury column, the height of the column varying with atmospheric pressure.
