Title: Why is heat ncreased in cell when ATP synthase inactivated?
Post by: noor123 on November 21, 2014, 08:49:04 AM

If the enzyme ATP synthase inactivates, it leads to increased heat in the cell, why is that?

Please show an attempt to answer a question first; that is a forum rule.  What is the thermodynamic driving force for the synthesis of ATP in the cell?

well, im not sure about the thermodynamic part of it, but all i can think of is that ATP synthase is supposed to make ATP from ADP right? so since its inactivated it cannpt do so, and so energy sort builds up? leading to heat formation?

The protonmotive force is responsible for ATP synthesis.  Both a pH gradient and a membrane potential contribute to the it.  Your explanation is a start, but it needs to be made more detailed IMO.
