Presentation Transcript

  1. Cellular Respiration Slowing Down Combustion Transferring Chemical Energy

  2. Cellular Respiration keeps us alive C6H12O6 + 6O2 ----> 6CO2 + 6H2O 36ATP Energy Released Energy released from one glucose molecule is transferred to 36 ATP molecules for use in cell work.

  3. Work with a partner to devise a memory trick for remembering the equation for cellular respiration. C6H12O6 + 6O2 ----> 6CO2 + 6H2O 36ATP Energy Released • Possibilities: • Chants • Songs • Concepts • “The Link” • Pictures • Patterns

  4. Slowing Down Combustion:Enzymes • Reduce the activation energy (no flame required). • Control the rate of reactions • Change Reactants into Products • Are not used up (recyclable).

  5. Enzyme Function • The substrate (molecule/s to be broken down or put together) fits in the active site. • The enzyme breaks or makes the bond. • The product/s are released.

  6. Join 2 or 3 others to “role play” the action of an enzyme. • Be sure to use all the words: • Enzyme • Substrate • Active Site • Product

  7. Transferring Energy: ATP Energy from glucose • Energy is required to add a 3rd phosphate onto ADP (adenosine diphosphate). • Energy is released when a phosphate is removed from ATP adenosinetriphosphate.

  8. Energy Graphs for ADP ATP Energy from Glucose Energy for cell work ATP ATP ADP ADP ATP stores small amounts of energy for use in cell work. 36 for every one glucose.

  9. Write a mnemonic using the initials ATP to remember its role in cellular respiration • A = • T = • P =

  10. Practice QuizClose your Journal • Write the balanced equation for cellular respiration. • What happens to the energy released? • How do enzymes control chemical reactions? • What is the role of ATP in cellular respiration?
