Energy Definition
The ability to do work
What does energy do
Flow through ecosystemes
Energy process?
Light Energy > Chemical Energy > Glucose > Chemical Energy > ATP > Mechanical > Heat
First Law of Thermal Dynamic
Energy is not created or destroyed, it changes forms.
Second Law of Thermal Dynamic
As energy changes forms, it goes from more organized to less organized
Entropy
Measure of randomniss
Potential Energy
Potential to do work
stored energy, not doing work at the moment
Kinetic Energy
Energy of motion
Chemical
Energy stored in bond between atoms
Calorie
Energy required to raise 1 ml to 1° C
Kilocalorie
Energy required to raise 1000 ml to 1 °C
What is Metabolism
The ability to get, store, and use energy
What are Metabolic Pathways
Series of chemical reactions using reactants to get intermediates and eventually a final product
Anabolic
Making big molecules from small molecules
Catabolic
Making small molecules from breaking down big molecules
