Energy Storageand Transformation ATP Info Biology 30 Mrs. S. Pipke-Painchaud
Where is energy released in the cell? • Mitochondria • Which carries out what important energy process? • Cellular Respiration UTMB http://cellbio.utmb.edu/cellbio/mitoch1.htm
Energy . . . • What is the common form of energy inside of cells? • ATP • Released energy is temporarily stored in high-energy ATP Molecules • ATP – Adenosine TriPhosphate
Animation Intro • Dr. Saul’s Biology • http://biologyinmotion.com/atp/index.html
What is ATP? • Composed of: • 5 – carbon sugar (ribose) • A nitrogen base (adenine) • Three (3) phosphate groups http://upload.wikimedia.org/wikipedia/commons/f/fd/ATP-3D-balls.png
ATPs Chemical Formula • C10H18O15N5P3 Image from Wikipedia: http://upload.wikimedia.org/wikipedia/commons/2/22/ATP-3D-vdW.png

The Process • When energy is needed from ATP, an enzyme breaks the bond between two phosphate groups, releasing one phosphate and energy. • The remaining molecule is ADP (Adenosine diphosphate)
Animation - process • Kaiser: http://student.ccbcmd.edu/~gkaiser/biotutorials/energy/atpan.html
When energy released by cellular respiration needs to be stored, a phosphate group is added to ADP forming ATP, and energy is stored in the bond between the phosphate groups.
ATP’s Lifespan • ATP Average Lifespan • 50 seconds
Demos • Human Example In Class • Blocks and Elastics model
