Explanation / Answer

1. This is thermodynamically favorable reaction

Consider a reaction in which the delta G (Gibbs Free Energy) value less than the zero (0) then that reaction is spontaneous and always proceed in forward direction & the reaction is said to be the thermodynamically favorable reaction. The energy of reactants always greater than the energy of the products in thermodynamically favorable reaction and always proceed in the forward direction and to reverse the reaction require the input of energy. The conversion of glyceraldehyde-3- phosphate to 3-phosho glycerate is a spontaneous reaction and has negative free energy change (-12Kcal/mol), it always favors the formation of 3-phosho glycerate.

2. This is an exothermic reaction

In any chemical reaction along with the products if energy is released then that reaction is called exothermic reaction. During The conversion of glyceroldyhyde-3- phosphate to 3-phosho glycerate 12Kcal of energy is released so it is an exothermic reaction

3. This is an example of a redox reaction.

Redox reactions are the reactions in which the electrons are transferred between the two species. The species which donate the electron is called reductant and the species which accepts electron is called oxidant. The conversion of glyceraldehyde-3- phosphate to 3-phosho glycerate is redox reaction. The glyceraldehyde-3- phosphate act as reductant and donate the electrons to NAD+ which is an oxidant. After accepting the electrons the NAD+ is reduced to NADPH.
