Out of $36$ ATP molecules produced per glucose molecule during respiration.
Complete oxidation of a molecule of glucose yields?
Number of ATP obtained at the end of Kreb's cycle?
How many ATP molecules will be produced when one molecule of $3$-phosphophoglyceric acid is completely oxidised?
The incremental oxidation of 1 molecule of glucose during cellular respiration produces 30 molecules of ATP according to the balanced equation:
$C _6H _{12}O _6+6O _2+30ADP+30P _i\rightarrow 6H _2O+6CO _2+30ATP$
ATP is then hydrolyzed by cells for a variety of biochemical processes.
Changes in free energy between glucose oxidation and ATP hydrolysis were compared. The table below illustrates the data collected:
Reaction | Change in Free Energy ($\triangle G$) |
---|---|
Glucose Oxidation | -686 kcal/mol |
ATP Hydrolysis | -13 kcal/mol |
