The totality of an organism's chemical reactions:
What is metabolism
100
The ability to do work:
What is energy
100
This type of molecule is also referred to as a biological catalyst:
What is an enzyme
100
The stored energy of position, location or structure:
What is potential energy
100
The type of system we are, evidenced by our constant exchange of materials and energy with the environment.
What is an open system
200
Metabolism in which energy is being consumed to build more complex molecules:
What is anabolism
200
Metabolism in which complex molecules are being broken to simpler molecules, and energy is being released:
What is catabolism
200
Metabolic pathways always end with these:
What are products
200
This is represented by Delta H
What is change in Enthalpy, or Total Energy of the system
200
Energy cannot be created or destroyed, only transferred or transformed:
What is the law of conservation of energy (the first law of thermodynamics)
300
The study of how energy flows through living systems:
What is bioenergetics
300
Enzymes lower this to cause a reaction to happen:
What is the activation energy
300
With each chemical reaction, the universe moves toward an increasing state of randomness and disorder
What is entropy (the second law of thermodynamics)
300
These types of molecules always end with the biological suffix -ase:
What are enzymes
400
Metabolic pathways always start with these:
What are reactants
400
Kinetic energy associated with the random movement of atoms or molecules:
What is heat
400
These proteins catalyze reactions in organic pathways:
What are enzymes
400
This is represented by Delta S:
What is change in entropy
400
In order for a reaction to be spontaneous, this value must be present:
What is negative change in free energy (negative delta G)
500
This type of potential energy is found in food molecules:
What is chemical energy
500
These types of reactions have a positive ^G, are not spontaneous, and consume energy in the reaction:
What are endergonic reactions
500
These types of systems eventually reach equilibrium, at which point they lose the ability to do work:
What are closed systems.
500
This type of reaction releases energy, and proceeds spontaneously with a negative ^G:
What is an exergonic reaction
500
This is the formula to calculate change in free energy:
What is ^G = ^H - T^S
