Also a precursor to DNA and RNA. This is the immediate energy source for muscle contraction, nerve impulses, and many chemical processes. It is consumed by being converted to [[Adenosine diphosphate (ADP)]] or [[Adenosine monophosphate (AMP)]], which are then regenerated by other processes. ## Production Multiple pathways: 1. Glycolysis, from glucose or glycerol 2. Citric acid cycle 3. Beta-oxidation 4. Ketosis 1 and 2 together are basically "cellular respiration" - glucose metabolism with oxygen, producing carbon dioxide. In plants, ATP is produced by photosynthesis in chloroplasts. [[Creatine]] plays a part in converting [[Adenosine diphosphate (ADP)]] back to ATP via donation of phosphate groups. ## Regeneration Continuous, via the same pathways.
