Metabolism terms Flashcards
1
Q
define: metabolism
A
the total of all chemical reactions occurring in an organism
2
Q
describe metabolic pathways
A
usually consist of multiple reactions, almost every step enzyme catalysed.
3
Q
define: catabolism
A
breakdown of complex molecules into simpler molecules - > energy released
4
Q
define: anabolism
A
synthesis of complex molecules from simpler molecules, energy required
5
Q
define: exergonic
A
cr that releases energy, overall
6
Q
define: endergonic
A
cr that requires energy input
7
Q
define: coupling of exergonic and endergonic reactions
A
when energy released from a catabolic reaction drives an anabolic reaction, which requires energy.
