Question

Which of the following is a true statement?

Answer 1

Answer:

a. Anabolic pathways build molecules, require energy, and are endergonic.

Explanation:

Anabolic pathway describes the metabolic reactions that build up complex molecules from simpler ones, typically via condensation (monomers covalently joined producing water as a by-product). It requires energy to construct new bonds, this means is endergonic.

The catabolic pathway, on the other hand, describes metabolic reactions that break complex molecules down into simple ones, typically via hydrolysis (consumption of water to break bonds within the polymer). It releases energy when these bonds are broken, this means it is exergonic.

Considering this information we can conclude that the correct answer is a. Anabolic pathways build molecules, require energy, and are endergonic.
