ATP ADENOSINE TRIPHOSPHATE

ATP SC Standard B-3.3: Recognize the overall structure of ATP – namely, adenine, the sugar ribose, & 3 phosphate groups – and summarize its function (including the ATP-ADP cycle).

ATP 1 of principal chemical cpds that cells use to store & release energy consists of: – Adenine(nitrogenous base) – Ribose (5-carbon sugar) – 3 phosphate groups

Structure of atp

atp phosphate groups reason why ATP is high nrg molecule – all 3 phosphate groups : fully charged battery – 3 rd phosphate bond highest nrg – 2 nd phosphate bond 2 nd highest nrg

adp adenosine diphosphate – partially charged battery

ATP cycle
