Presentation Transcript

  1. The power within… Adenosine Triphosphate ATP

  2. Why? • Most imp. biochem. mol. for ENERGY SUPPLY • Main energy currency for organisms • Large no. of processes can occur because of it

  3. How? • First, let’s see what it looks like… Phosphate Groups Adenine (Nitrogenous base) 5C Ribose Sugar

  4. Energy released; ADP formed

  5. ATP – ADP Cycle: • Last P bond breaks from ATP, releasing needed energy1 • ADP now exists (a weaker molecule), and a free P • ATP ADP + Phosphate + energy • ADP / P are recycled. Energy2 is used to reattach ADPtoP, remaking ATP • ADP + Phosphate + energy ATP Released energy1much greater than reattaching energy2

  6. ATP ADP + P+ + energy
