Chemistry Of  Life Chemistry Of Life Presentation Transcript

  • Living Environment Transport and life in a cell By- Justin Ehrenpreis
    • Active Transport-
    • *Lower to higher concentration
    • * Makes energy
    • Passive Transport-
    • *Higher to Lower concentration
    • * Diffusion
    • * No energy required
    • Diffusion of water through a membrane is….
    • osmosis
    • Organic Compounds-
    • *contain Hydrogen and Carbon
    • * 4 major compounds are…
    • 1- Carbohydrates
    • 2- Lipids (fats)
    • 3- Proteins
    • 4- Nucleic Acids
    • Inorganic Compounds-
    • Lack Carbon and Hydrogen combination
    • Examples-
    • 1- Water
    • 2- Salts
    • C arb oh ydrates -
    • * main source of energy for all cell activities
    • Made of C arbon, H ydrogen, and O xygen
    • CH2
    • Includes Starches and sugars
    • Three types of Carbohydrates-
    • 1- Monosaccharide
    • 2- Disaccharide
    • 3- Polysaccharide
    • The basic unit of building blocks are….
    • Monosaccharide
    • Monosaccharide
    • Simple sugar
    • Example-
    • Glucose
    • Disaccharide-
    • Double sugar
    • Dehydration Synthesis-
    • Process where 2 compounds combine and water removed from it
    • Polysaccharides
    • Many compounds
    • Lipids-
    • Store energy in living things
    • Contain C arbon, H ydrogen, and O xygen
    • greater than 2:1
    • *Examples- *Fatty acids and glycerol
    • Fats + oils = Lipids
  • Pinocytosis
    • -cell drinking
    -dissolves molecules
  • Phagocytosis
    • cell eating
    • Like Pac man
  • Proteins
    • Carbon, Hydrogen ,Oxygen and Nitrogen
    • Amino Acids -
    • Building blocks of proteins
    • 2 amino acids =
    • Dipeptide + Water
  • Nucleic Acids
    • Composed of…
    • nucleotide chains
    • That has…
    • genetic information.
    • Nucleic acids are found in…
    • Living cells and viruses
  • Summary
    • Carbohydrates
    • Ch2
    • Monosaccharides
    • Lipids
    • 1 Glycerol + 3 Fatty Acids
    • Proteins
    • Symbol is N
    • Amino Acids
    • R represents…
    • Any group
  • What do compounds look like?
    • Has 6 sides
    • Looks like a Hexagon
    • Some times without any lines
  • Review By Justin Ehrenpreis
  • ___________saccharides…
    • Mono is…
    • One
    • Di is…
    • Two
    • Poly is…
    • many
  • What saccharide is this…
  • Answer is….
    • Monosacchride
  • What saccharide is this….
  • Answer is…
    • Polysaccharide
  • What saccharide is this…
  • Answer is…
    • Disaccharide
  • What is the basic unit of building blocks?
    • Monosaccharide
  • What takes care of cell eating ?
  • Answer is…
    • Phagocytosis
  • What takes care of cell drinking and dissolves molecules ?
    • Pinocytosis
  • 4 major compounds are…
    • 1- Carbohydrates
    • 2- Lipids (fats)
    • 3- Proteins
    • 4- Nucleic Acids
