The standard free-energy change for this reaction in the direction written is 23.8 kJ/mol. The concentrationsof the three intermediates in the hepatocyte of a mammal are: fructose 1,6-bisphosphate,1.4X10-5 M; glyceraldehyde 3-phosphate, 3X10-6 M; and dihydroxyacetone phosphate, 1.6X10-5 M. At body temperature (37C), what is the actual free-energy change for the reaction

The actual free-energy change for the reaction  -8.64 kJ/mol.

Explanation:

The given reaction is as follows.

  Fructose 1,6-bisphosphate Glyceraldehyde 3-phosphate + DHAP

For the given reaction, is 23.8 kJ/mol.

As we know that,

Here,    R = 8.314 J/mol K,       T =

                                                    = (37 + 273) K

                                                    = 310.15 K

Fructose 1,6-bisphosphate = M

Glyceraldehyde 3-phosphate = M

DHAP = M

Expression for reaction quotient of this reaction is as follows.

    Reaction quotient =

        Q =

            =

Now, we will calculate the value of as follows.

                      =

                      = -8647.73 J/mol

                      = -8.64 kJ/mol

Thus, we can conclude that the actual free-energy change for the reaction  -8.64 kJ/mol.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
