Answer:
See explanation below.
Explanation:
Catabolism and anabolism are <u>both biochemical reactions that are part of important process of metabolism.</u>
Anabolic and catabolic pathways 'need each other,' that is, <u>the energy that is produced from catabolism is utilized by anabolism.</u>
Anabolic reactions use <u>simple molecules to build complex molecules</u>, whereas the role of catabolism is <u>to break the large molecules and transform them into smaller ones.</u>
<u>Example of Anabolism</u>
<em>Photosynthesis:</em>
- The reaction between CO2 and H2O to form glucose and oxygen.
<u>Example of Catabolism</u>
<em>Digestion:</em>
- Breaking down of large molecules to produce energy.
