metabolism Flashcards
1
Q
what is metabolism?
A
the chemical process that build-up and break down molecules within cells
2
Q
what is an endergonic reaction?
A
a process which absorbs free energy from the surroundings, e.g. photosynthesis.
- have products with more stored energy than the reactants of the reaction
- typically anabolic reactions
(anabolism is the process of making large molecules from smaller ones)
3
Q
what is an exergonic reaction?
A
a process with a net release of free energy, e.g. burning of a substance
- they have reactants with more stored energy than the products of the reaction
- they are typically catabolic reactions
(catabolism is the process of breaking down large molecules into smaller ones)
