What is metabolism?
The sum of all the biochemical reactions that takes place in a cell is known as metabolism.
Metabolism means the total number of all the reactions that takes place in a cell as catabolism or anabolism.
• Catabolism means breakdown of large molecules in to smaller ones by usually releasing energy. As in cellular respiration.
• Anabolism means synthesis of complex molecules by usually gaining energy. Just like in Photosynthesis.
