Presentation Transcript

  1. 11/17/2010 ATP

  2. Controlled Energy Flow • What is the safest way to get out of a building 5 story building? • Walking down stairs • Jumping out the window • Why?

  3. Controlled Energy Flow • What is the safest way to get out of a building 5 story building? • Walking down stairs • Jumping out the window

  4. Controlled Energy Flow • The reason why going down stairs is less dangerous is because the speed of the drop is controlled. • The fast, big drop is changed into smaller, slower drops. vs.

  5. The same thing happens in your body. • If you released all of the potential energy stored in matter at once, your body would light up in flames.

  6. How does your body release energy safely?

  7. The Function of ATP • When you digest food, your body transfers small packets of energy from the food that you ate to a biological molecule called Adenosine Triphosphate (ATP). ATP ATP ATP ATP

  8. The Function of ATP • When you digest food, your body transfers small packets of energy from the food that you ate to a biological molecule called Adenosine Triphosphate (ATP). ATP ATP ATP ATP

  9. The Function of ATP • After all of the energy is squeezed out of the food that you ate and transferred to ATP molecules, the dead matter is excreted.

  10. The Function of ATP • After all of the energy is squeezed out of the food that you ate and transferred to ATP molecules, the dead matter is excreted.

  11. The Function of ATP • ATP is found in every cell of your body. • Every cell in your body uses ATP to do work. • ATP is cellular energy. • Your body is entirely powered by ATP

  12. The Function of ATP • ATP is found in every cell of your body. • Every cell in your body uses ATP to do work. • ATP is cellular energy. • Your body is entirely powered by ATP

  13. Practice • Write “Adenosine Triphosphate” • On your paper • On your neighbor’s paper

  14. The Structure of ATP • ATP is made of: • Adenine (A) • Ribose (sugar) • 3 phosphates (P)

  15. The Structure of ATP • ATP is made of: • Adenine (A) • Ribose (sugar) • 3 phosphates (P)

  16. The structure of ATP Prefixes: Mono 1 Di 2 Tri 3

  17. The structure of ATP Prefixes: Mono 1 Di 2 Tri 3

  18. The Structure of ATP • Energy is stored in between the phosphate bonds.

  19. The Structure of ATP • Energy is stored in between the phosphate bonds.

  20. The Structure of ATP • When a phosphate is broken off of ATP, energy is released. • This is kinetic energy that can be used to do work.

  21. The Structure of ATP • When a phosphate is broken off of ATP, energy is released. • This is kinetic energy that can be used to do work.

  22. The Structure of ATP • Energy is stored in the new phosphate bond. • This is potential energy that is stored.

  23. The Structure of ATP • Energy is stored in the new phosphate bond. • This is potential energy that is stored.

  24. Exit QuestionsWrite the answers at the bottom of your notes. • What does ATP stand for? • Why is ATP important in the cell? • When ATP is broken down, what molecule is created? • Where is the most energy stored in ATP? • A • B • C • D C D A B
