Photosynthesis and Cellular Respiration Review

Equation for Photosynthesis

• 6CO2 6H2O ?(sun) C6H12O6 6O2
• Reactants 6CO2 6H2O
• Products C6H12O6 6O2

3
Cellular Respiration Equation

• C6H12O6 6O2 6CO2 6H2O
• Products 6CO2 6H2O
• Reactants C6H12O6 6O2

PHOTOSYNTHESIS PATHWAYS

• LIGHT REACTION
• ---gtsunlight needed to break water molecule (H2O)
  so hydrogen (H2) can be used to make glucose
  (C6H12O6)
• ---gt oxygen (O2) from water is released into the
  air.

5
PHOTOSYNTHESIS PATHWAYS

• DARK REACTION
• ---gt hydrogen (H2) combines with carbon dioxide
  (CO2) to make glucose (C6H12O6).
• --gt without the hydrogen from the light reaction
  there would be no glucose.

6
Anaerobic

• Doesnt require oxygen.
• Alcoholic Fermentation Lactic Acid Fermentation
  are anaerobic processes

7
Locations

• Photosynthesis Chloroplasts of plants cells
• Cellular Respiration Mitochondria of eukaryotic
  cells

8
Organisms

• Photosynthesis plants
• Cellular respiration animal and plant cells

9
Function of ATP

• ATP (adenosine triphosphate)- is the source of
  energy used in cells
• To release energy from ATP, one phosphate group
  is broken off-releases potential energy stored in
  the chemical bond.

10
Release of Energy

• Energy is released when phosphate groups are
  removed.
• The new molecule is called ADP (adenosine
  diphosphate)

11
Inhibition of photosythesis

• Green light because green is reflected not
  absorbed by plants

12
Light intensity

• More intense, more photosynthesis takes place.

13
Necessary materials for photosynthesis

• Light, water and carbon dioxide

14
Pigment

• Chlorophyll
