• ATP Review (Diagram/ 4.2)
• Main energy source of ALL living things.
• Adenosine Triphosphate.
• All carbohydrates (sugars) are turned into ATP in
  the mitochondria
• Releases energy for the cell by breaking a
  phosphate bond and becoming ADP.

Cellular Respiration

• Occurs in both plants and animals! ALL LIVING
  THINGS!!!!!
• Mitochondria
• Break down organic compounds(food) into
  energy(ATP).
• Reactants (IN) Glucose and Oxygen
• Products (OUT) Water, Carbon Dioxide and Energy
• C6H12O6 O2 ? CO2H2Oenergy
• Begins with glycolysis.
• Glucose is broken down into two smaller
  molecules.
• This reaction produces 6 ATP molecules.
• The products of glycolysis will then take one of
  two pathways
• Aerobic Respiration OR Anaerobic Respiration
  (fermentation)

Aerobic Respiration Anaerobic Respiration (fermentation)
Requires Oxygen No Oxygen
Produces 32 ATP Produces 2 ATP
Larger organisms Usually Small organisms
Two types
7
Two types of fermentaion (no oxygen)

• Lactic Acid Fermentation
• An enzyme changes sugar into energy and lactic
  acid.
• Used in the production of yogurt and cheese.
• Lactic acid builds up in muscle cells when they
  are put under strenuous conditions.
• Alcoholic Fermentation
• Changes sugars into energy and ethyl alcohol.
• Some plant cells and unicellular organisms use
  alcoholic fermentation.
• Used in the production of bread and wine

• ONLY COMPLETE THE SECTIONS
• Title
• Write Purpose
• Copy the data table
• Graph
• Conclusion Sentences or Paragraph
• Work with a partner but record YOUR own data.

• How does light work?
• Light travels in waves.
• The wavelength of these waves determines the
  property of the light.
• The entire spectrum of light waves is called the
  Electromagnetic Spectrum.
• Only a small part of this spectrum is the type of
  light we can see (visible spectrum).
• Different materials react differently to these
  wavelenghts.
• Ex. A red shirt is seen as red because it
  absorbs all colors in the visible spectrum but
  reflects red.
• Why should you wear a white shirt on a hot day??

10

• Electromagnetic Spectrum - total range of
  electromagnetic waves
• AM RadioFM Radio
• Radar
• Microwaves
• Infrared
• Visible-ROYGBIV
• UV
• X Ray
• Gamma Rays
• Different materials react differently to visible
  wavelenghts.
• Ex. A red shirt is seen as red because it
  absorbs all colors in the visible spectrum but
  reflects red.

11

• Chlorophyll
• Compound found in plant leaves (chloroplasts)
• Reflects green light and absorbs reds and blues.
• Accessory Pigments
• Carotenoids yellow, orange and brown
• Why is it important for the plant to have
  pigments other than chlorophyll?
• Do all plants have accessory pigments? Why cant
  you see them all year long?

12
Remember

• Only plants have chloroplasts.
• Autotrophs make their own food.
• Heterotrophs get (eat) their food.
• All living things (heterotrophs and autotrophs)
  need to make ATP with respiration.

13

• Photosynthesis PLANTS!!
• Conversion of light energy into chemical energy
  that is stored as organic molecules, usually
  carbohydrates.
• Occurs in the chloroplasts
• What do plants need to grow?
• CO2 H2O Energy ? C6 H12 O6 O2

14
Plant Anatomy

• Water comes into a plant through the roots and is
  carried to the leaf in the xylem.
• Sunlight is absorbed by the chloroplasts in leaf
  cells.
• Carbon Dioxide comes in through the stomata
  (little mouth) on the leaves. The oxygen leaves
  through the same openings.
• Extra water leaves through stomata
  (transpiration).
• Waxy cutin/cuticle keeps the plant from drying
  out

15
How do plants get reactants?
16

• Check/redo homework
• Practice Question 4,5,6

17
Rate of photosynthesis

• Concentration of reactants.
• Do you talk to your plants???
• Temperature/Rainfall
• This affects transpiration (plant sweat) and
  water uptake.
• Amount of chloroplasts

18
Autotrophs(plants) turn the suns energy into
sugar.Heterotrophs(animals) use the sugar from
autotrophs for ATP energy.What is the ultimate
energy source on Earth????
19
Energy Practice / 4.2 / 10 points

• Coach Workbook
• Lesson 12 1-4 AND Lesson 13 1-4
• Photosynthesis and Respiration Word Sort
• Three columns term, descriptions,
  example/picture
• Mrs. Handest must check and sign your notebook.
  Work as a partnership.
• When you finish you should work on U3HW4,
  Vocabulary and/or Study Guide!

20
Activity!

• Comic
• Create a comic strip that shows the relationship
  between autotrophs and heterotrophs.
• A Day in the Life of Sugar
• Write a story from the point of view of a glucose
  molecule in the leaf of a plant cell.
• Diagram
• Create a diagram that shows the relationship
  between the sun, photosynthesis, respiration
• All must include
• Descriptions of photosynthesis and respiration
  locations, reactants and products. (10pts)
• Correct information and pathways. (8pts)
• Neat and creative (2pts)

21

• Overview-the easy version
• Photosynthesis has two parts Light reaction and
  dark reaction.
• The light reaction
• Uses sunlight to break a water and make ATP for
  the dark reaction. NADPH accepts an electron to
  carry to the dark reaction. Oxygen is released
  as a waste.
• Occurs in the thylakoid.
• The dark reaction (Calvin Cycle)
• Carbon dioxide is changed into glucose(food)
  using ATP and the electrons from NADPH from the
  light reaction.
• Occurs in stroma.
