|
The amount of energy (in joules) required to convert all the molecules in 1 mole of a reacting substance from the ground state to the transition state
|
Activation energy, delta G double dagger
|
|
|
The phase of intermediary metabolism concerned with the energy-requiring biosynthesis of cell components from smaller precursors
|
Anabolism
|
|
|
One of the five kingdoms of living organisms; includes many species that thrive in extreme environments of high ionic strength, high temperature, or low pH
|
Archaebacteria
|
|
|
One of the five kingdoms of living organisms. Eubacteria have a plasma membrane but no internal organelles or nucleus
|
Eubacteria
|
|
|
The phase of intermediary metabolism concerned with the energy-yielding degradation of nutrient molecules
|
Catabolism
|
|
|
An atom with substituents arranged so that the molecule is not superimposable on its mirror image
|
Chiral center
|
|
|
The spatial arrangement of an organic molecule that is conferred by the presence of either (1) double bonds, about which there is no freedom of rotation, or (2) chiral centers, around which substituent groups are arranged in a specific sequence. Configurational isomers cannot be interconverted without breaking one or more covalent bonds
|
Configuration
|
|
|
The spatial arrangement of substituent groups that are free to assume different positions in space, without breaking any bonds, because of the freedom of bond rotation
|
Conformation
|
|
|
The filamentous network providing structure and organization to the cytoplasm; includes actin filaments, microtubules, and intermediate filaments
|
Cytoskeleton
|
|
|
A chemical reaction that consumes energy (that is, for which delta G is positive)
|
Endergonic reaction
|
|
