Flashcards in Metabolism Deck (15):
Flow of Energy
-the capacity to do work
--work-movement, transport, or making things
What general forms is Energy found in?
Energy of movement/ motion
-light, heat, electrical
-Chemical bonds (in living things)
Laws of Thermodynamics
1. Law of Conservation
2. Law of Entropy
Law of Conservation
Energy cannot be created of destroyed
Law of Entropy
Disorder will increase
-As energy changes forms more energy is changed to forms we cannot use.
Putting something together, making something bigger
Breaking something down
An exergonic reaction powering an endergonic reaction.
Gives off energy
Heat is measured to measure the energy of something.
- Calorie is the unit of energy measurement
-The amount of heat it takes to raise 1gram water from 14.5C to 15.5C (1 degree Celsius)
-Calorie= 1,000 calories or Kcal= 1kg water raised 1 degree Celsius.
Energy of Activation
Needed to get the reaction going
