Metabolism |
The sum total of all chemical reactions in an organism |
|
|
|
Anabolic reactions |
Complex molecules are made from simple molecules energy input is required |
Building blocks |
|
|
Catabolic reactions |
Complex molecules are broken down into simpler ones and energy is released |
|
|
|
Energy |
Equals ability to promote change or do work |
|
|
|
What are the two forms of energy |
Kinetic energy and potential energy |
|
|
|
Kinetic energy |
The energy of movement |
|
|
|
Potential energy |
Due to structure or location, is stored energy - as chemical bonds, concentrates gradient, charge imbalance |
|
|
|
Chemical energy |
The energy in a Molecular bonds is a form of potential energy |
|
|
|
Laws of thermodynamics |
Thermo equals energy dynamics equals change apply to all matter and all energy transformation in the universe also transforms energy to sustain life which is a homeostasis |
|
|
|
First law of thermodynamics |
- law of conservation of energy , - energy cannot be created or destroyed, - the total energy before and after the conversion and is the same - example solar power , heat, light, chemical, electrical |
|
|
|
Second law of thermodynamics |
Transfer of energy from one form to another increases the entropy of a system -, - as in trophy and creases less energy is available for organisms to use to promote change , - no energy transformation is 100% efficient |
|
|
|
Total energy |
Usable energy + unusable energy , - energy transformation involves an increase in entropy disorder that cannot be harnessed to do work, - free energy (G) equals amount of energy available to do work gives me energy |
