Concept explainers
MATHEMATICAL Using the information in Table 20.2, calculate
Interpretation:
The standard free energy change for the given biological reaction is to be determined.
Concept introduction:
Oxidation is the addition of an electronegative element or the removal of an electropositive element in a chemical reaction.
Reduction is the addition of an electropositive element or the removal of an electronegative element in a chemical reaction
The chemical reaction in which oxidation process and reduction process takes place and reduction take place simultaneously is called a redox reaction.
The relation between standard free energy change and standard reduction potential for the biological process is shown as follows:
Here,
Answer to Problem 8RE
Solution:
Explanation of Solution
The half reactions that are paired during the redox reaction are shown below, along with their standard free energy change:
The aim reaction for which the standard free energy is to be calculated is shown as follows:
As, the aim reaction can be calculated as follows:
Therefore the standard free energy is calculated as follows:
Hence, the standard free energy of the given biological reaction will be calculated.
The standard free energy of the given biological reaction is
