Metabolism Flashcards
Metabolism
Flow of Energy
- the capacity to do work
- -work-movement, transport, or making things
What general forms is Energy found in?
- Kinetic
- Potential
Kinetic Energy
Energy of movement/ motion
-light, heat, electrical
Potential Energy
Stored Energy
-Chemical bonds (in living things)
Laws of Thermodynamics
- Law of Conservation
2. Law of Entropy
Law of Conservation
Energy cannot be created of destroyed
-Changes forms
Law of Entropy
Disorder will increase
-As energy changes forms more energy is changed to forms we cannot use.
Anabolic Reaction
Putting something together, making something bigger
-Endergonic
Catabolic Reaction
Breaking something down
- Exergonic
- -not spontaneous
Reaction Coupling
An exergonic reaction powering an endergonic reaction.
Endergonic
Requires energy
Exergonic
Gives off energy
Energy measurement
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
Types of Chemical reactions
