  1. Adenosine tri-phosphate stores energy in the Phosphorus bonds

    ADP has 2, ATP 3 (Di, Tri..) so it stores energy in going from ADP to ATP version of the molecule, then recovers energy on the release/return to ADP from ATP


  2. i learned that stuff last year, i never understood it that well. im sorryy why dont you call a friend or look it up

  3. ATP stands  for Adenosine triphosphate, N9 of  adenine ring connected to ribose ring at C1,  and three phosphates are connect to the ribose ring atC5, it is negatively  charged.

    Energy is produced as release of  the  end phosphate ; ATP to ADP

    As result of  hydrolysis of ATP which releases  a phosphor group to water.

  4. the nucleotide ATP is composed of the nitrogen base adenine a 5 carbon sugar called ribose and 3 phosphate.the significance of the structure is lies in its two energy rich phosphate groups.

    when hydrolysis breaks one of these energy rich bonds the release energy is made available to the cell in an accessible form.

    ATP + WATER --> ADP + P+ ENERGY

  5. Well, where to begin?

    ATP is an efficient energy carrier because the triphosphate bonds are unstable; this means there is a shift from ATP to ADP in a non-equilibrium environment. Hydrolysis of ATP to ADP + Pi will release -30.54 kJ/mol under standard conditions, a fairly high amount. Energy released by any molecule in this circumstance is dependent on the distance from equilibrium the molecules are in, so by keeping the level of ADP in the body at a much lower magnitude, ATP becomes a very energy efficient molecule.

    The structure of ATP is exactly as it's named - adenosine triphosphate. You have an adenosine, which is an adenine and a ribose ring, linked to a chain of three phosphates separated by ester bonds.

    The stored energy technically comes from the hydrolysis of ATP to ADP, breaking off a phosphoryl group.

    It is released by many mechanisms, though the one you'll encounter most in biological systems is pairing into another reaction to make the overall change in energy favorable to spontaneity, allowing the reaction to proceed forward. This movement of phosphates makes most of the reactions in the body possible, since they require movement to a more complex state (and require energy as a result).
