Question

Those chemical reactions in which energy is obtained and trapped from the environment are called __________.

a) Catabolic reactions
b) Anabolic reactions
c) Exergonic reactions
d) Endergonic reactions
e) Metabolic reactions

Answer 1

Endergonic reactions in organisms are called anabolic reactions and absorb energy to build bigger molecules. Catabolic reactions in organisms are called exergonic reactions and break down molecules to release energy.

Step-by-step explanation:

Endergonic reactions in organisms are called anabolic reactions. These reactions absorb energy and build bigger molecules from smaller ones. An example of an anabolic reaction is the joining of amino acids to form a protein.

Catabolic reactions in organisms are called exergonic reactions. These reactions break down molecules into smaller units and release energy. An example of a catabolic reaction is the breakdown of glucose during cellular respiration, which releases energy that cells need to carry out life processes.

So, the correct answer is option d) Endergonic reactions.
