metabolism Flashcards
1
Q
what is catabolism?
A
generates energy by breakdown of molecules = Atp
2
Q
what is anabolism?
A
consumes energy by building up of molecules, uses energy
3
Q
what is FREE ENERGY?
A
energy within a living cell
4
Q
what does a positive delta G show?
A
not spontaneous energy = anabolic = Exergonic
5
Q
what does a negative delta G show?
A
spontaneous = catabolic = endergonic
6
Q
example of a catabolic reaction?
A
cellular respiration
7
Q
example of an anabolic reaction?
A
formation of a peptide bond
8
Q
what are coupling reactions?
A
when exergonic and endergonic reactions are both used to ‘do work’
