Presentation Transcript

  1. 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 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. Learning Target • I can explain the flow of energy (ATP) • Agenda • Catalyst • ATP • An example of ATP • Practicing ATP • Exit Slip

  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 • 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

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

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

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

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

  15. 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.

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

  17. Uses of ATP • Energy for mechanical functions (movement, muscle contraction). • Active Transport • Building and breaking of large molecules. Carbs, lipids, proteins, nucleic acid • Drives chemical reactions in cells

  18. Sources of Energy • Organisms are classified according to the way they get their food. • Autotrophs: organisms that produce their own food (energy)… • Some examples are… • Heterotrophs: organisms that obtain energy from foods they consume… • Some examples are…

  19. Autotrophs vs. Heterotrophs AUTOTROPHBOTH HETEROTROPH

  20. Autotroph or Heterotroph?

  21. Autotroph or heterotroph?

  22. Autotroph or Heterotroph?

  23. Autotroph or Heterotroph?

  24. Energy • Energy is stored in the chemicalbonds of energy-storing compounds. • Energy is released when the chemical bonds of these compounds are broken.

  25. Fully Energized ATP Enzyme that makes ATP= ATPase After Energy is Released ADP Compounds That Store Energy
