Catabolic pathway
|
Metabolic pathway that releases energy by breaking down complex molecules to simple molecules.
|
Anabolic pathway
|
Consume energy to build complicated molecules from simpler ones.
|
Kinetic energy
|
The energy of motion.
|
Potential energy
|
Stored energy
|
The first law of Thermodynamics is the principle of...
|
Energy can be transferred and transformed but cannot be created or destracted. (principle of conservation of energy)
|
The second law of Thermodynamics involves changes in...
|
Every energy transfer or transformation increases the entropy of the universe.
|
Entropy
|
A quantitative measure of disorder or randomness, symbolized by S.
|
Exergonic reaction
|
A spontaneous chemical reaction in which there is a net release of free energy.
|
Free energy
|
The portion of a system's energy that can perform work when temperature is uniform throughout the system. The change in free energy of a system is calculated by the equation
where T is absolute temperature.
|
Neuron
|
A nerve cell; the fundamental unit of the nervous system, having structure and properties that allow it to conduct signals by taking advantage of the electrical charge across its cell membrane.
|
Polymer
|
A long molecule consisting of many similar or identical monomers linked together.
|
Polypeptide
|
A polymer (chain) of many amino acids linked together by peptide bonds.
|
Monomer
|
The subunit that serves as the building block of a polymer.
|
Activation energy
|
Energy required to break bonds in the reactant
|
Why are enzyems said to be specific?
|
Because of their shape and bonding site that can only bond to the matching pair.
*shape determines the function of the enzyme.
