PHOTOSYNTHESIS

1
PHOTOSYNTHESIS CELLULAR RESPIRATION

• How energy is made within..

2
Autotrophs convert light energy into glucose
(sugar)

• Photo light
• Synthesis to make

3
Photosynthesis Equation

6CO2 6H2O Light Energy ? C6H12O6 6O2

I. Light Absorption

• Photosynthesis (light reactions) occur in
  chloroplast
• Light waves travel as waves
• Objects absorb different wavelengths of color
• The color you see is the color that is being
  reflected back at you.
• ROYGBIV

5
Pigments absorb light

• Photosynthesis requires light and chlorophyll

III. Photosynthesis Reactions

• A. Light Dependent Reaction

• B. Calvin Cycle
• (light independent Reaction)

• Needs Sun

• Does Not Need Sun
• Carbon Fixation occurs (putting carbon into
  molecules)

8
V. Rate of Photosynthesis

• Rate is affected by
• 1. Sunlight
• 2. Temp
• 3. Carbon Dioxide

Cellular Respiration
How animals make energy or ATP..
10
Cellular Respiration and Photosynthesis
Relationship

• They are opposites in the energy world and in
• Cellular Respiration occurs in animals in the
  mitochondria
• Photosynthesis occurs in plants in the
  chloroplast

Cellular Respiration Equation

C6H12O6 6O2?6CO2 6H2O ATP
12
Cellular Respiration

• There are 3 main cycles where ATP is produced

Glycolysis
Krebs Cycle
Electron Transport Chain
13
Anaerobic vs. Aerobic
Some cycles require oxygen some do not

• Anaerobic do not require Oxygen
• Glycolysis
• Fermentation (ATP not made)
• Aerobic requires Oxygen to make ATP
• Krebs Cycle
• ETC (Electron Transport Chain)

14

2 types Fermentation

• Alcoholic

• Lactic Acid

• Used for
• Yeast in bread
• Wine
• Sauerkraut
• Products
• CO2
• NAD
• Alcohol

• Used by
• Muscles when over exercised
• Products
• NAD
• Lactic Acid

15
Living things need energy

• Our bodies have a lot of work to do every day
• Moving muscles,
• Building essential molecules
• Transporting substances across cell membranes.

16
Where do we get energy?

• Food provides the energy living things need to
  grow and reproduce.
• Food is the source of the material our cells use
  to build new molecules
