pegasus10 Posted October 27, 2018 Posted October 27, 2018 Hello, I was wondering if there is a difference between the value of deltaG° and deltaG°' (with the apex; referring to pH=7 and [Mg2+]=1mM) for a given reaction. For example, the reaction ATP + H2O = ADP + Pi has a deltaG°' of -30.5 kJ/mol (Lehninger), but what is the value of deltaG° for this reaction? Thanks in advance!
BabcockHall Posted October 30, 2018 Posted October 30, 2018 At pH 0 (where protons are 1 M in concentration) ATP, ADP, and Pi will all have very different protonation states than they do at pH 7. I am not sure what the value of deltaG° will be, but I am fairly certain that it will be different.
