Solution
An endergonic reaction is one that requires energy to proceed. It is characterized by a positive change in Gibbs free energy.
Among the choices given:
-
Anabolic reactions: These are indeed endergonic reactions. They involve the building up of complex molecules from simpler ones, a process that requires energy.
-
Biosynthetic reactions: These are also endergonic reactions. They involve the synthesis of complex molecules in living organisms, again requiring energy.
-
Catabolic reactions: These are typically exergonic, not endergonic. They involve the breakdown of complex molecules into simpler ones, a process that releases energy.
-
Arrangement of monomers into polymers: This is an example of an anabolic or biosynthetic reaction, and thus would be endergonic.
-
Anabolic and biosynthetic: As mentioned above, both of these types of reactions are endergonic.
So, the endergonic reactions among the choices given are anabolic reactions, biosynthetic reactions, the arrangement of monomers into polymers, and anabolic and biosynthetic reactions.
