Presentation Transcript

  1. N.J. Biology End of Course State Test Review

  2. Biology Started With: • Macromolecules- the molecules of life! • Lipids- fats, phospholipids of cell membranes- CHO. • Proteins- found in tissues, cell membranes, determined by DNA and assembled by RNA, CHON. • Carbohydrates –used for energy. CHO • Nucleic Acids- genetic material-DNA, RNA, CHOPS.

  3. Where did these elements come from?

  4. Natural Cycles- Carbon Cycle

  5. Nitrogen Cycle

  6. Phosphorous Cycle

  7. All living things need water! • Evaporation, precipitation, transpiration.

  8. So how do these elements get into living things? • Food Chains and food webs! • Starts with producers-autotrophs- photosynthesis. • Consumers- heterotrophs, cellular respiration.

  9. Life processes- • cellular respiration is essentially the reverse reaction of photosynthesis. • The formula for photosynthesis is 6 H2O + 6 CO2 + light energy ----------> C6 H12 O6 + 6 O2 and the formula for cellular respiration is C6 H12 O6 + 6 02 ----------> 6 H2O+ 6 CO2+ energy

  10. Continued- • You can see that the products of photosynthesis fuel cellular respiration and the products of cellular respiration fuel photosynthesis. • Photosynthesis uses energy from sunlight to build glucose and release oxygen from carbon dioxide and water. Cellular respiration combines oxygen with glucose in the mitochondria to produce ATP; water (along with a little heat) and carbon dioxide are produced as well.

  11. What Else? • Cells! • Prokaryotes- no nuclues. Eukaryotes- nucleus

  12. Transport • Passive- no energy, osmosis and diffusion. • Active – energy, pinocytosis, phagocytosis, Na/K pump.

  13. Genetics! • DNA, RNA, chromosomes,genes, forms of inheritance

  14. Cell Division! • Mitosis and meiosis.

  15. Evolution! • Change over time. • Charles Darwin- Survival of the Fittest!

  16. Ecology! • Food Chains and Food Webs • Symbiotic Relationships • Biomes
