Metabolism Flashcards
1
Q
Anabolism
A
building small molecules into larger molecules (small to big)
2
Q
Example of anabolism
A
DNA synthesis, DNA replication, protein synthesis
3
Q
Catabolism
A
breaking down large molecules into smaller ones (big to small)
4
Q
Example of catabolism
A
the digestive system, glycolysis, the Krebs cycle

Q
Substrate
A
the molecule(s) that is changed by the enzyme

Q
Enzymes
A
- usually proteins (complicated, delicate, unique 3D structure)
- biological catalyst
- reused
- usually end in “-ase”
