Cell Metabolism Flashcards
(13 cards)
Metabolic pathway
A chemical reaction w/ a definite start and end and purposeful steps
Metabolism
All the chemical reactions in an organism
Catabolic reaction
Metabolic pathway where molecules are broken down and energy is released (digestion)
Anabolic pathway
Builds more complex molecules out of less complex molecules
Energy
The ability to cause change
4 types of energy
Kinetic, thermal, potential, chemical
Kinetic energy
Energy an object has due to movement
Thermal energy
Heat
Potential energy
Energy due to the position of an object
Chemical energy
Energy stored in chemical bonds
Thermodynamics
Conversion of energy from one form to another
1st law of thermodynamics
Energy can be transferred and transformed, but not created or destroyed
2nd law of thermodynamics
Every energy transfer or transformation increases the entropy of the universe
