Question

Sapling Learning When considering free energy change, biochemists usually define a standard state, the biochemical standard state, which is modified from the chemical standard state to fit biochemical applications. Determine both. Note that if you answer any part of this question incorrectly, a single red X will appear indicating t one or more of the phrases are sorted incorrectly.

Explanation / Answer

When studying biochemical processes, biochemists use the term biochemical standard state which is different from the chemical standard state in some aspects.

Classification of terms given below to biochemical, chemical or both types of standard states are shown below.

Biochemical standard state

pH = 7

dGo' (some text use dGo'')

The change in [H2O] is assumed to be significant

Constant value for [Mg2+]

Chemical standard state

temperature at 298 K

[H+] = 1 M

Both

initial concentration of reactants and products is 1 M

pressure is 1 atm

dGo
