Discussion Overview

The discussion revolves around the theoretical calculation of how many moles of ATP can be produced from the oxidation of one mole of glucose, specifically focusing on the use of Gibbs free energy (delta G) in this context. The scope includes homework-related inquiries and mathematical reasoning regarding biochemical energy transformations.

Discussion Character

  • Homework-related
  • Mathematical reasoning

Main Points Raised

  • One participant states the need to use delta G for glucose oxidation to determine the theoretical ATP yield.
  • Another participant provides a value for delta G of glucose oxidation as -916 kJ/mol but expresses uncertainty about how to proceed with the calculation.
  • A different participant suggests that the energy produced from glucose oxidation cannot exceed the energy stored in ATP, implying a need for an energy balance approach.

Areas of Agreement / Disagreement

Participants express uncertainty about the calculations and the necessary values to use, indicating that the discussion remains unresolved with multiple viewpoints on how to approach the problem.

Contextual Notes

Limitations include the dependence on specific conditions for delta G values and the lack of clarity on whether participants should reference tables or perform calculations based on other data.

Homework Statement


assuming that all the energy released by the oxidation of one mole of glucose to carbon dioxide and water can be stored in the form of ATP, how many moles of ATP can be theoretically produced from ADP at 37 C? Use delta G since it tells you how much work a reaction could do or requires. ( P is a phosphate group, ADP is adenosine dephosphate, ATP is adenosine triphosphate)


Homework Equations


ADP ^-3 + H ^+ + P--> ATP ^-4 + H20 delta G= 31.4 KJ/mol


The Attempt at a Solution



I don't know how to start solving it, help

You will need delta G for glucose oxidation. Not knowing the circumstances it is hard to tell if you are expected to find it in tables or calculate from some other data.
 
delta G is -916 kj/mol for Glucose. i don't know where to start or how to...help?
 
Now it is a simple energy balance - amount of energy produced from glucose oxidation can't be higher than amount of energy stored in ATP.
