Presentation Transcript

  1. Energy Storageand Transformation ATP Info Biology 30 Mrs. S. Pipke-Painchaud

  2. 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

  3. 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

  4. Animation Intro • Dr. Saul’s Biology • http://biologyinmotion.com/atp/index.html

  5. 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

  6. ATPs Chemical Formula • C10H18O15N5P3 Image from Wikipedia: http://upload.wikimedia.org/wikipedia/commons/2/22/ATP-3D-vdW.png

  8. 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)

  9. Animation - process • Kaiser: http://student.ccbcmd.edu/~gkaiser/biotutorials/energy/atpan.html

  10. 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.

  11. ATP’s Lifespan • ATP Average Lifespan • 50 seconds

  12. Demos • Human Example In Class • Blocks and Elastics model

  13. Resources • Enzymes: • http://www.uic.edu/classes/bios/bios100/lecturesf04am/lect04.htm
