At 10 m M glucose, however, 10 μ M of the drug reduced the islet ATP content but not the ATP/ADP ratio, while 50 μ M of the drug, besides lowering the ATP content, also reduced the ATP/ADP ratio. Diazoxide (0.5 m M ) increased the islet ATP content in the absence of glucose, an effect not seen in the presence of 10 m M glucose. ATP. ATP. (Adenosine TriPhosphate) is like cellular “cash in the bank”. The cell will break ATP down and get the energy out to “spend” when it needs to do cellular work (such as active transport). When ATP is broken down, a phosphate group is lost (lost as Pi) and. ADP (Adenosine DiPhosphate) results. ATP is thus like a battery that is charged. As cells oxidize food (e.g., sugar) the energy in the sugar is captured and stored in the phosphate bonds of ATP. When a chemical reaction requires an input of energy, ATP breaks down to ADP, releasing the energy in the phosphate bond. ADP is like a spent battery. Key Differences Between ATP and ADP. The molecular formula of ATP is C 10 H 16 N 5 O 13 P 3. As a result of hydrolysis one hydrogen, two oxygen and one phosphate group eliminate from the ATP, and the molecular formula of ADP will represent as C 10 H 15 N 5 O 10 P 2.
