Q: Exothermic reactions in organisms are called what?


Read this paragraph and choose the correct option from the provided answers:

Exothermic reactions in organisms are called catabolic reactions . These reactions break down molecules into smaller units and release energy. An example of a catabolic reaction is the breakdown of glucose, which releases energy that cells need to carry out life processes. Endothermic reactions in organisms are called anabolic reactions . These reactions build up bigger molecules from smaller ones. An example of an anabolic reaction is the joining of amino acids to form a protein. Which type of reactions—catabolic or anabolic—do you think occur when your body digests food?.

 Choices:

- nuclear reactions

- nebular reactions

- biogenic reactions

- catabolic reactions


A:
catabolic reactions
