4
Q
Cellular metabolism
A
The sum of all the chemical reactions taking place in all living cells, two reactions: catabolic & anabolic
5
Q
Anabolic reactions
A
assemble simple molecules into more complex molecules. This pathway requires a lot of energy, making them an endergonic (energy requiring) reaction. In this reaction bonds are formed.
