The chemical formula for the expenditure/release of ATP energy can be written as: a) in chemicalese: ATP ----> ADP + energy + Pi. b) in English Adenosine Triphosphate produces Adenosine diphosphate + energy + inorganic Phosphate. An analogy between ATP and rechargeable batteries is appropriate.
Urinal drug tests: Urine is analyzed to search for traces of nicotine. While it may only persist in the body for 3-4 days after consuming tobacco products urine tests have been known to discover traces of nicotine for up to 15-20 days even with passive smokers.
