1 The power within… Adenosine Triphosphate

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… 5C Ribose Sugar Adenine (Nitrogenous base) Phosphate Groups

7  Energy released; ADP formed

8 ATP – ADP Cycle: 1. Last P bond breaks from ATP, releasing needed energy 1 2. ADP now exists (a weaker molecule), and a free P ATP ADP + Phosphate + energy 3. ADP / P are recycled. Energy 2 is used to reattach ADP to P, remaking ATP ADP + Phosphate + energy ATP Released energy 1 much greater than reattaching energy 2

9 ATP ADP + P + + energy
