1. Carbohydrates & Cell Energy Honors Biology ch 4 & 15

2. Biosphere: The spacetime that life inhabits Autotrophs: Convert light energy into chemical energy Ex: plants, algae, & bacteria

3. Matter (Carbon) cycles through the biosphere

4. Carbon is an element: 4 valence electrons Ability to make 4 stable covalent bonds

5. Macromolecules are large organic carbon compounds Carbohydrates Lipids Proteins Nucleic Acids

7. Monosaccharide Simple (one sugar) carbohydrates ex: glucose (C 6 H 12 O 6 ) Polysaccharide Complex carbohydrates ex: starches (C 1n H 2n O 1n )

8. Biological Functions: Short term energy Structural support Cell tags (antennae) Human Acquisition: Grains Fruits

9. Plants: Cellulose, Sucrose, Fructose… Animals: Glycogen, Chitin…

10. How are these molecules constructed in the biosphere

11. Light energy CO2 + H2O C6H12O6 + O2 (Carbon dioxide) (water)(glucose) (oxygen)

13. Light energy CO2 + H2O C6H12O6 + O2 (Carbon dioxide) (water)(glucose) (oxygen)

14. Plant Organs: Leaves are responsible for photosynthesis Plant Cells: Contain chloroplast organelles

15. Stroma: Fluid inside the chloroplast Thylakoid: Saclike structure that contains chlorophyll

16. Pigment that absorbs light energy

17. Very complex molecular process: matter cycles and energy flows

18. Stage 1: Light Dependent Reactions (thylakoid) Water is split apart by light & Oxygen is produced Stage 2: Light Independent Reactions (stroma) Carbon dioxide is fixed into Glucose

19.

20. Aerobic

21. Autotrophs convert light energy into chemical energy CO2 + H2O + light energy  C 6 H 12 O 6 + O2

22. Process that converts glucose energy into ATP energy Occurs in ALL living cells

23. Adenosine Triphosphate is a usable form of cell energy

24. Type 1: Aerobic Respiration Requires O 2 Type 2: Anaerobic Respiration Does not require O 2

25. Chemical process which occurs in the Mitochondria C 6 H 12 O 6 + O 2  CO 2 + H 2 O + ATP

26. Matrix: Fluid inside the mitochondrion Cristae: Internal membrane in the mitochondrion

28. Stage 1 Glycolysis (cytoplasm) C 6 H 12 O 6 is broken down into smaller carbon molecules Stage 2 Krebs Cycle (matrix) Smaller carbon molecules are broken down into CO 2

29. Stage 3 Oxidative Phosphorylation (Cristae) O2, E-, & H+ from Stage 1 & 2 make ATP molecules

30. Start with Chemical Energy (Glucose) Convert to Usable Chemical Energy (many ATP) Use ATP and release Heat Energy

32. Anaerobic

33. Process that converts glucose energy into ATP energy Occurs in ALL living cells Type 1: Aerobic Respiration Requires O 2 Type 2: Anaerobic Respiration Does not require O 2

35. Many organisms live without O2 and/or mitochondria

36. Chemical process which produces ATP without O2 Stage 1 Glycolysis Glucose  smaller carbon molecules Stage 2 Lactic Acid Fermentation C 6 H 12 O 6  C 2 H 5 OH + CO 2 + ATP OR Stage 2 Alcoholic Fermentation C 6 H 12 O 6  CH 3 CHOHCOOH + ATP
