Differentiate between exergonic and endergonic in terms of free-energy calculations

What will be an ideal response?


Answer: A positive change in free energy (ΔG0') means the reaction needs energy input to occur (called endergonic), whereas a negative ΔG0' needs no energy input and actually releases excess energy (called exergonic).

The development of normal maternal behavior in female mice depends on interactions between the female and her young and the presence of a gene called fosB. In mice with functional fosB genes, a sequence of events occurs after babies are born.

Arrange the events in their normal sequence following the birth of baby mice for a wildtype female.  ___  Female crouches over young and retrieves them if they leave the nest. ___  Auditory, olfactory, and tactile signals about the young are sent to the hypothalamus. ___  Neural circuitry within the hypothalamus is modified, facilitating maternal behavior. ___  Female inspects newborns. ___  The gene fosB is activated, producing protein that activates other genes.
