Presentation Transcript

  1. Cell Respiration Cornell Notes Essential Question: How do all organisms use stored chemical energy to perform the functions necessary for life? Phoenix Curriculum Guide, Quarter 2, Unit 3, Essential Standard 3.4 Understand the relationship between photosynthesis and cellular respiration and its role in providing energy for organisms

  2. Directions for Cornell Notes The blue question goes on the left side of your notes. Vocabulary and definitions marked in redgo on the right side of your notes. Answer the summary questions at the end.

  3. Phosphate groups Adenine P P P High Energy bonds Ribose • What is Adenosine Triphosphate (ATP)? Forms high energy bonds – give off lots of energy when broken

  4. How does ATP work? • Types of Reactions • Endergonic = needs energy (building molecules, repair, movement) • Exergonic = gives off energy (breaking down molecules) • Free energy = energy that cells can use to do work • Moving the energy • ATP acts as a rechargeable battery to move energy from one type of reaction to another.

  5. What is ADP? Energy used for movement, growth, repair, building new molecules. Energy supplied from cellular respiration and the breakdown of glucose. ATP Adenosine Diphosphate- one broken bond of phosphate to release energy ADP

  6. What are the facts about ATP? ATP is used by all organisms. ATP is made during cellular respiration. ATP is formed in the cytoplasm and mitochondria of the cell. Most ATP is made in the mitochondria. ATP

  7. Cellular Respiration How to Make Energy!

  8. What does cellular respiration do? Produces energy trapped in high energy bonds of ATP using glucose and oxygen

  9. Who does cellular respiration? All living organisms

  10. Where does cellular respiration occur? eukaryotes = mitochondria and cytoplasm prokaryotes = cytoplasm

  11. Why is cellular respiration important? ATP provides the energy to run all other cellular reactions

  12. How does cellular respiration create ATP? When bonds break in glucose, energy is released. This energy is used to form the high energy bonds in ATP.

  13. When does cellular respiration occur? All of the time BUT slowly, in a series of steps. This is important so energy is not released in one big BOOM!

  14. enzymes What is the formula for Cellular Respiration? 6H2O + 6CO2 + energy C6H12O6 + 602 reactants catalysts products Glucose and oxygen become water, carbon dioxide and energy The free energy is used to create high energy bonds in ATP.

  15. Stages of Cellular Respiration

  16. What is Glycolysis? • Used by all living things • Occurs in cytoplasm • Anaerobic (requires no oxygen) • Starts with glucose and breaks it into two • Releases energy which is used to change ADP + P into ATP • 1 glucose provides enough energy to create 2 ATP molecules

  17. What is Aerobic Respiration? • Occurs after glycolysis • Requires oxygen; used by most living things • Occurs in mitochondria • Composed of two stages – citric acid cycle and electron transport system • Breaks glucose up into carbon dioxide and water, releasing lots of energy • 1 glucose helps create 36 ATP molecules

  18. What is the role of respiration in the carbon cycle? • All living things release CO2 back into the atmosphere. • CO2 is then absorbed by plants, algae, and cyanobacteria, through a process called photosynthesis

  19. Summary Questions • What is the difference between ATP and ADP? • What is the end product of cellular respiration? • Where does cellular respiration occur at in eukaryotes? 4. Where does the CO2 go once it leaves a living organism?

  20. Summary Questions What is the difference between ATP and ADP? ATP has 3 phosphates and ADP has only two phosphates. 2. What is the end product of cellular respiration? Water, carbon dioxide, and energy 3. Where does cellular respiration occur at in eukaryotes? Mitochondria and cytoplasm. 4. Where does the CO2 go once it leaves a living organism? Back into the atmosphere
