7.3 Flashcards
Metabolism
All the chemical reactions of life
Anabolic
Making larger molecules out of smaller ones
Catabolic
Making smaller molecules out of larger ones
Exergonic
When released energy is greater than required energy in a reaction.
Endergonic
When required energy is greater than released energy in a reaction.
Hydrolysis
The process in which a polymer is broken into its monomers.
Dehydration Synthesis
The process in which two or more monomers are joined to make a polymer.
The ATP Cycle
ADP + PO3OH (anabolic reaction) -> ATP
ATP + POOR2OH (catabolic) -> ADP
Description of a graph of exergonic and endergonic reactions.
Exergonic: Released energy rises and falls in a short bell curve
Endergonic, Required energy rises and falls in a short bell curve
Is an anabolic reaction endergonic or exergonic? Catabolic reactions too.
Anabolic = Endergonic
Catabolic = Exergonic
Which parts of the ATP process correlates with the vocab?
The condensation reaction - anabolic/exergonic reaction
The phosphate transfer - catabolic/endergonic reactions.
Why do endergonic reactions need an exergonic reaction to come before.
The exergonic reaction, with its small boost in released energy, supplies the endergonic reaction.
One example of this is in coupled reactions.
