Front Back
Releases energy, so the change in free energy is negative.
Exergonic
A type of energy exchange between systems that acts as a result of a difference in potentials other than temperature, such as volume or pressure.
Work
All portions of the universe except for the system.
Surroundings
The process by which the body synthesizes needed biochemicals.
Anabolism
Heat exchange at constant pressure; its a state function.
Enthalpy
A metabolic pathway in which glucose is broken down into two molecules of pyruvate with a net gain of 2 ATP molecules.
Glycolysis
A "measure of disorder" but is more properly viewed as a measure of the number of energy states into which a system may be distributed.
Entropy
A noncovalently associated group of proteins which catalyze a multistep process without the intermediates entering other pathways.
Complex
A small, organic molecule of cellular respiration that functions in the release of carbon dioxide gas and the transfer of electrons and protons to another coenzyme.
CoA
Metabolically irreversible reactions within a chemical pathway.
Control points
The specific portion of the universe under study.
System
A key feature of living organisms. The process uses reactants of higher energy (e.g., ATP) to drive what would otherwise be an energetically unfavorable reaction.
Reaction coupling
Results when cells oxidize NADH by reducing pyruvate (the end product of glycolysis) through fermentation. It diffuses out of the cell to avoid buildup.
Lactate
An inorganic substance that acts with and is essential to the activity of an enzyme; examples include metal ions and some vitamins.
Cofactors
A series of proteins that transfer electrons in cellular respiration to generate ATP.
Electron transport chain
