1. Why do you get hungry?

2. Energy
All organisms use energy to carry our the chemical activities that allow them to live, grow, and reproduce.
Cellular Energy
Cellular Respiration
Photosynthesis
Fermentation

3. Photosynthesis Occurs in plants and is bottom of food pyramid.
Is the process of changing sunlight into energy (food).

4. Pigments Are molecules in plant cells that absorb the energy of light.
Chlorophyll: the pigment that is green in chloroplasts.

5. Photosynthesis 6CO2 + 6H20 + light energy C6H1206 + 602 (Food)
Carbon dioxide
Water
Glucose
(Carbs)
Oxygen

6. I don’t have lungs to breath!
Cellular Respiration
Process of breaking down food so the energy from your food can be converted for cell use.
Uses Oxygen
Not the same as breathing.
Oxy. is necessary for process & carbon dioxide is waste.
Respiration happens in plants & animals
I don’t have lungs to breath!

7. Cellular Respiration & Energy
C6H12O6 + 6O2
6CO2 + 6H2O + ATP
Glucose
Oxygen
Carbon
dioxide
Energy
Water
(Energy)

8. Metabolism All the chemical activities in the organism: Making food
Breaking down food
Moving material in/out of cells
Building cells

9. Fermentation Muscle Fermentation Lack of oxy. causes burning feeling
Small amt. of ATP (energy) is made
Released as lactic acid.
Sugar
Fermentation
Yeast make CO2 and alcohol.
Bubbles of CO2 form bread.
