What is metabolism?
What is metabolism?
All chemical reactions that maintain the living state of cells and organisms.
What is anabolism?
What is anabolism?
Assimilation of molecules and complex structures from the building blocks of life. This also requires energy.
What is catabolism?
What is catabolism?
Breakdown of molecules to obtain the anabolic 'building blocks' of life and substrates for energy. It is a precursor for the anabolic process.
