4.2- Metabolism Flashcards
Metabolism Definition
the chemical processes that occur within a living organism in order to maintain life
Anabolic Definition
marked by or promoting metabolic activity concerned with the biosynthesis of complex molecules (such as proteins or nucleic acids)
Catabolic Definition
marked by or promoting metabolic activity concerned with the breakdown of complex molecules (such as proteins or lipids) and the release of energy within the organism
Exergonic Definition
(of a metabolic or chemical process) accompanied by the release of energy
Endergonic Definition
(of a metabolic or chemical process) accompanied by or requiring the absorption of energy, the products being of greater free energy than the reactants
Hydrolysis Definition
the chemical breakdown of a compound due to reaction with water
Synthesis Definition
the production of chemical compounds by reaction from simpler materials
How is an anabolic reaction related to an endergonic reaction?
The building of complex molecules, such as sugars, from simpler ones is an anabolic process and is endergonic
How is a catabolic process related to an exergonic reaction?
On the other hand, the catabolic process, such as the breaking down of sugar into simpler molecules, is exergonic
If a reaction is a catabolic reaction it is also a ________
endergonic
If a reaction is anabolic it is also _____
exergonic
