ATP abd ADP

Post by krystalgiles » Wed Dec 14, 2005 7:52 pm

hey does anyone know which molecule holds more energy and why? Also, when is energy from ATP moleculer released?

Energy is stored in organic bonds. ADP has 2 phosphate groups that bond to the rest of the chemical while ATP has 3.

As for your second question: whenever it is needed. Think about processes that require energy

bio-energetic molecules

*There are several molecules in the cell that "store" energy in catalytic cycles. The most frequently cited ones are ATP and ADP; however, the molecules that harbor More energy than ATP are called NADH and NADPH. In the Krebs cycles their unique phospho-diester bonds harbor and release more kcals of energy than ATP.

Actually, its ATP and ADP that have the phosphodiester bonds. The nicotinamides and flavanoids don't store energy in the same sense as ATP and ADP and the like (creatine, etc.).

the nicotinamides and flavanoids are electron transporters, not energy releasing substances like ATP.
