Energy Utilization (definition)
|
Organisms take in and transform energy to do work
|
|
|
Energy Utilization (flowchart)
|
Sunlight -> Plants -> Animals
|
|
|
2 transformations of forms of energy
|
1. Photosynthesis
2. Cellular Respiration |
|
|
Photosynthesis (flowchart)
|
Solar energy -> Chemical energy (carbohydrates)
|
|
|
Photosynthesis (equation)
|
6 CO2 + 6 H2O -> C6H12O6 + 6 O2
|
|
|
Where does photosynthesis occur?
|
In the chloroplasts
|
|
|
Cellular respiration (flowchart)
|
Chemical energy (carbohydrates) -> Chemical energy (Adenosine triphosphate [ATP])
|
|
|
Cellular respiration (equation)
|
C6H12O6 + 6 O2 -> 6 CO2 + 6 H2O + ATP
|
|
|

|
|
Breakdown (hydrolysis) of ATP...
|
releases energy
|
|
|
Hydrolysis of ATP (equation)
|
ATP + H2O -> ADP + Inorganic Phosphate + Energy
|
|
|
ADP
|
Adenosine Diphosphate
|
|

ATP is renewable (Yes/No)
|
Yes
|
|
|
Classification of organisms based on how they get their energy
|
1. Autotrophs
2. Heterotrophs |
|
|
Autotrophs (characteristics)
Example? |
1. Do not consume other organisms
2. Make their own organic molecules e.g. Plants |
|
|
Heterotrophs (characteristics)
Example? |
1. Consume other organisms
2. Cannot make their own food e.g. Animals |
|
|
Homeostasis (define)
Examples? |
1. Organisms regulate their internal environment
2. Do not live in a vacuum e.g. Sweating: animals use this process to cool down body temperature Shivering: to warm body |
