Question

Reactions that build larger molecules in the cell are called ___________; reactions that break down molecules into smaller ones are called ___________.

Answer 1

Anabolic Reactions and Catabolic Reactions  

Explanation:

Anabolic Reactions -

• Anabolic reactions are reactions that build larger molecules from smaller ones while the catabolic reactions are the reactions that break down molecules into smaller ones.  
• Anabolic reactions are also called biosynthetic reactions because they synthesize larger molecules from smaller molecules or constituent parts.
• The energy used by these reactions to proceed is ATP.
• Anabolic reactions occur in cells for the synthesis of new proteins and other reactions.

Catabolic Reactions -

• Catabolic reactions are the reaction that includes the whole pathway of reaction that breaks down larger molecules into smaller units.
• These molecules are oxidized to release energy or sometimes used in other anabolic reactions occurring in the cell.
