Presentation Transcript

  1. ATP Cycle Anna, Nofal, Will

  2. (Adenosine triphosphate) • An adenine-containing nucleoside triphosphate that releases free energy when its phosphate bonds are hydrolyzed • The phosphate bonds are all negatively charged so they are coiled and unstable • This energy is used to drive reactions in cells that require energy (endergonic) What is ATP?

  3. Molecular structure: three phosphate groups, one ribose group, and one adenine group

  4. The ATP and water form a hydrolysis reaction • This hydrolysis reaction separates a phosphate tail creating ADP • This generates 7.3 kcal of energy per mole of ATP ATP Cycle

  5. When ATP is separated into ADP, it releases energy. This is called an exergonic reaction • Some of this released energy is used to fuse ADP and a Pi together to make ATP again • This means the ATP cycle is continuous How is ATP used and regenerated?

  6. A working muscle cell recycles its entire pool of ATP in less than a minute. This means that 10 million molecules of ATP are used up and regenerated every second for every cell. Fun fact
