1. PHOTOSYNTHESIS
AND
RESPIRATION

2. PHOTOSYNTHESIS
THE PROCESS OF CHANGING LIGHT ENERGY INTO CHEMICAL ENERGY
LIGHT E
CHEMICAL E
( glucose )

3. LIGHT E TRAVELS TO THE CHLOROPLASTS IN PLANT CELLS AND IS CHANGED INTO CHEMICAL ENERGY (GLUCOSE) BY CHLOROPHYLL USING WATER (H2O) AND CARBON DIOXIDE (CO2). THE WASTE PRODUCT GIVEN OFF IS OXYGEN (O2).
SUNLIGHT
( LIGHT ENEGY )
WATER ( H2O )
CARBON DIOXIDE ( CO2)
OXYGEN ( O2 )
CHEMICAL ENERGY ( GLUCOSE )

4. PHOTOSYNTHESIS FORMULA
Light energy
6 CO H C6H12O O2
Carbon Dioxide
Water
Glucose
Oxygen + +

5. CELLULAR RESPIRATION
THE PROCESS OF BREAKING DOWN FOOD TO RELEASE ENERGY
OXYGEN + GLUCOSE
ENERGY WASTE PRODUCTS
CARBON DIOXIDE WATER
ATP ( adenosine triphosphate )

6. CELLULAR RESPIRATION FORMULA
C6 H12O6 + 6O CO H20 + ENERGY
glucose
oxygen
carbon dioxide
water
(ATP)

7. photosynthesis and respiration
depend on each other
Photosynthesis makes glucose and gives off oxygen which is necessary for cellular respiration to occur.
Respiration gives off water and carbon dioxide which is necessary for photosynthesis to occur

8. CO2
H20
respiration
photosynthesis
GLUCOSE O2

9. FERMENTATION
THE BREAKDOWN OF SUGARS TO MAKE ATP IN THE ABSENCE OF OXYGEN
TWO TYPES OF FERMENTATION, BOTH RELEASE A SMALL AMOUNT OF ATP BUT HAVE DIFFERENT WASTE PRODUCTS:
1. LACTIC ACID
2. ALCOHOL AND CO2

10. ANIMALS AND SOME BACTERIA AND FUNGUS
IN MUSCLES, A SMALL AMOUNT OF ATP AND THE WASTE PRODUCT LACTIC ACID ARE RELEASED WHICH CAUSES SORE AND TIRED MUSCLES
(bacteria) –
IN MILK, A SMALL AMOUNT OF ATP AND THE WASTE PRODUCT ALCOHOL ARE RELEASED WHICH CAUSES MILK TO BECOME MORE SOLID AND GIVES IT A DIFFERENT FLAVOR

11. YEAST FERMENTATION
(yeast)
YEAST CELLS RELEASE A SMALL AMOUNT OF ATP AND THE WASTE PRODUCTS ALCOHOL AND CO2
CO2 MAKES THE BREAD RISE AND THE ALCOHOL BURNS OFF DURING BAKING

12. AEROBIC AND ANAEROBIC AEROBIC cellular respiration
uses oxygen to release ATP
ANAEROBIC
fermentation
does not require oxygen and produces very little energy
