Chapter 19: Q17P (page 662)

Calculate the free energy change for moving a proton from the thylakoid lumen to the stroma when 螖辫贬=3.4,螖蠁=0, and T=250C

Short Answer

Expert verified

The free energy change will be -19.4KJ/mol for moving a protein from the thylakoid lumen to the stroma.

Step by step solution

01

Free energy change

The free energy change is the amount of energy released in the reaction of reactants to products under favorable conditions.

02

Information available from the question

From the given information, 螖辫贬=3.4,螖蠁=0 , and T=250C

03

Calculating the free energy change

In order to calculate the change in free energy, the following equation is employed.

螖骋0'=2.3RT*[pH(site1)鈭�pH(site2)]+螖蠁螖骋0'=2.3*(8.314J/Kmol*298K)*(鈭�3.4)+0=鈭�19372J/mol=-19.4kJ/mol

04

Free energy is negative;

The pH is estimated to be negative as the proton is being transferred from the lumen of the thylakoid (lower pH) to the stroma of the thylakoid (higher pH).

Hence, the value of free energy change is estimated to be 螖骋0'=-19.4kJ/mol
