Transcript

  • Slide 1
  • Chapter 8.1-Energry and Life
  • Slide 2
  • Chemical Energy In Cells -Is stored as ATP -Adenosine triphosphate - Adenine, ribose, 3 phosphate groups -Bonds in ATP can be broken to release energy -Is re-usable -ATP can be re-formed to store energy over and over -Is similar to a rechargeable battery
  • Slide 3
  • Slide 4
  • Adenosine diphosphate (ADP) Phosphate group (P) + + = = Adenosine triphosphate (ATP)
  • Slide 5
  • Slide 6
  • Autotrophs and Heterotrophs -Autotrophs make their own food -Also called producers -Photosynthesizers -Heterotrophs eat or consume food or nutrients -Also called consumers -Herbivores -Carnivores -Omnivores -Autotrophs form the basis of any chain, and make life on Earth possible
  • Slide 7
  • Chapter 8.2 p. 232 An overview of photosynthesis
  • Slide 8
  • Photosynthesis Reaction -Occurs in chloroplasts -In symbols: 6CO 2 + 6H 2 O + light C 6 H 12 O 6 + 6O 2 -In words: Carbon Dioxide + Water + Light Sugar + Oxygen
  • Slide 9
  • Chapter 9.1 p. 251 An overview of cellular respiration
  • Slide 10
  • Cellular Respiration Reaction -Occurs in mitochondria -In symbols: 6O 2 + C 6 H 12 O 6 + 6H 2 O + 6CO 2 + ATP -In words: Oxygen + Sugar (Glucose) Carbon Dioxide + Water + Energy
  • Slide 11
  • Chapter 9.1 p. 253 Comparing photosynthesis and cellular respiration
  • Slide 12
  • Comparing Photosynthesis and Cellular Respiration Photosynthesis -Removes CO 2 from the atmosphere -Releases O 2 into the atmosphere -Turns CO 2 into food (sugar) Cellular Respiration -Releases CO 2 into the atmosphere -Removes O 2 from the atmosphere -Uses O 2 to turn sugar into energy
