Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
When molecules are being built by chemical reactions it is called
A
anabolism
B
catabolism
C
fermentation
D
respiration
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.

Detailed explanation-3: -Anabolism pertains to a sequence of chemical reactions that constructs or synthesizes molecules from smaller units. Catabolism includes a series of degradative chemical reactions that break down complex molecules into smaller units. Anabolic reactions usually require an input of energy.

Detailed explanation-4: -Anabolism is a biochemical process in metabolism where the simple molecules combine to generate complex molecules. This process is endergonic, which means it is not spontaneous and requires energy to progress the anabolic reaction.

Detailed explanation-5: -Anabolic pathways build complex molecules from simpler ones and typically need an input of energy. Building glucose from carbon dioxide is one example. Other examples include the synthesis of proteins from amino acids, or of DNA strands from nucleic acid building blocks (nucleotides).
