Which of the following statements about anabolic pathways is true?

- They release energy by degrading polymers to monomers.

They consume energy to build up polymers from monomers.

They are usually spontaneous chemical reactions.

They decrease the entropy of the organism and its environment.

They consume energy to build up polymers from monomers.

Explanation:

Anabolic reactions are the metabolic reactions performed in the body which synthesizes the large molecules from the small molecules or synthesizes polymers from the monomers.

The synthesis of polymers requires energy which is provided during the reaction by ATP, NADH or NADPH molecules.

The examples of anabolism include the synthesis of biomolecules like the nucleic acid from the nucleotides, the synthesis of proteins from the amino acids, the synthesis of sugars from the carbon dioxide and water and many others.

Thus, the selected option is the correct answer.

They consume energy to build up polymers from monomers.

Explanation:

Metabolism may be defined as all the biochemical reactions that are present in the living organisms. These reactions are important for the sustenance of the life.

Two main type of metabolic reactions are catabolic reaction and anabolic reactions. The anabolic reactions includes the formation of the large product from the small molecules. The large compounds are synthesized in the cells in the anabolic reactions.

Thus, the correct answer is option (2).
