Science Skills W.S.

• Which are better to eat (for energy)?
• Plants or meat
• Which are better for our planet?
• Three hundred trout are needed to support one man
  for a year.  The trout, in turn, must consume
  90,000 frogs, that must consume 27
  million grasshoppers that live off of 1,000 tons
  of grass.  -- G. Tyler Miller, Jr., American
  Chemist (1971)

Energy Flow

• Graphic Organizer

11
Test Review

• Heterotrophic vs autotrophic organisms
• Source of all energy
• ATP structure
• Location of energy
• Use of energy
• Heat released too!!!

12
Test Review

• Photosynthesis
• Pigments
• Colors absorbed and reflected
• Types of pigments
• Electrons
• From?
• Where do they go?
• How are they replaced?
• Oxygen
• Where does it come from?
• Where does it go?
• ATP and NADPH
• Calvin cycle

13
Test Review

• Cellular respiration
• Glycolysis
• 2 ATP formed
• 2 NADH formed
• Glucose split
• 2 pyruvate formed
• Fermentation
• Absence of oxygen
• Alcoholic
• Lactic acid

14
Test Review

• Aerobic respiration
• Presence of oxygen
• Krebs cycle
• Know the handout (like Calvin cycle)

15
Prokaryotic Cell Reproduction

• Binary fission
• Produces identical offspring
• Steps
• 1. DNA is copied
• 2. Cell is divided

Terminology

• Somatic Cell
• Any cell in the body that isnt a gamete
• Gamete (Germ cell or sex cell)
• Sperm or ovum
• Gene
• Segment of DNA used as instructions to code for a
  trait
• 1000s per chromosome

17
Chromosomes

• Made from DNA
• Genetic material that directs activities and
  determines characteristics
• Formed from chromatin
• Right before mitosis
• Chromatin coils up into rods

18
Eukaryotic Cell Reproduction(Mitosis)

• Each chromosome (at this point) is made up of 2
  identical chromatids
• Joined strands of identical duplicated genetic
  material
• Joined at centromere
• Chromatids separate and each cell has identical
  information
• Formed in S phase of cell cycle

Sets of chromosomes

• Each human somatic cell has 23 pairs of
  chromosomes (46 total)
• Homologous chromosomes
• Each pair is called homologous
• Similar in size, shape and genetic content
• Not identical!
• One from each parent
