7.1  ATP Production

The ATP molecules that provide energy to eukaryotic cells are produced during glycolysis and cellular respiration.

 During ATP production, the cell takes in sugar and O2 and release CO2, water and energy. This is summarized below.



Cellular respiration chemical reaction



The breakdown of glucose during cellular respiration releases energy.

The slow burning of glucose in the cell allows the energy to be removed slowly and ultimately stored as ATP. Imagine burning gasoline (glucose) in a generator to make electricity (ATP).

ATP is made is made by two different methods during cellular respiration. The diagram above shows a high energy phosphate

group (top center with red line below it) getting pulled off of one molecule and then being added to ADP to make ATP in a process sometimes abbreviated as SLP.
