Summary Introduction

To analyze:

The energy yield when thermophilic bacteria metabolizes 150mM (Milli Mole) formate to produce 20mM bicarbonate ion and 10mM hydrogen gas in deep-sea hydrothermal vents at 80°C, ΔG°’ = -2.6KJ/mole (Kilojoule/mole).

Introduction:

Gibb’s free energy is a measure to determine the availability of energy to perform a function. Two types of factors affect the energy change (ΔG) of a reaction. They are internal properties of a reaction and external factors such as environmental conditions, concentration of reactants and products. Internal properties include ΔH (enthalpy change) and ΔS (entropy change). Environmental factors include pressure and temperature.

Ozone in the lower atmosphere is a pollutant that can form by the following reaction involving the oxidation of unburned hydrocarbons:CH4(g) + 8 O2(g)-------->CO2(g) + 2 H2O(g) + 4 O3(g)Use the standard free energies of formation to determine ΔG°rxn for this reaction at 25 °C.
The standard free energy change for the reaction catalyzed by phosphoglucomutase is -7.1 kJ/mol. Calculate the equilibrium constant for the reaction. Calculate AG at 37°C when the concentration of glucose-1-phosphate is 1-mM and the concentration of glucose-6-phosphate is 25-mM. Is the reaction spontaneous under these conditions?

The oxidation of glucose to CO2 and water is a major source of energy in aerobic organisms. It is a reaction favored mainly by a large negative enthalpy change.                                                                                        C6H12O6(s) + 6O2(g) →6CO2(g) + 6H2O(l)                                                  ∆H° = -2816 kJ/mol ∆S ° = +181 J/mol .
