Can someone explain the difference between endergonic and endothermic? Thanks!

These two terms refer to different thermodynamic state functions. An endergonic reaction is one that has a positive change in Gibb's free energy (non-spontaneous). An endothermic reaction is one that has a positive change in enthalpy (requires heat).

“Gonic” refers to change in Gibbs free energy and “thermic” refers to change in enthalpy. When delta G is less that 0 it is spontaneous and exergonic and when it is greater than 0 it is not spontaneous and endergonic

Endergonic refers to a positive change in Gibbs Free energy while endothermic refers to a positive change in enthalpy.

I agree with the above answers. Endergonic refers to the consumption of Gibb's free energy (delta G > 0) by the system. Endothermic refers to the consumption of enthalpy (heat under constant pressure conditions) by the system (delta H > 0).

An endergonic reaction is where energy is absorbed, therefore making delta G positive. Exergonic is when energy is released, therefore delta G would be negative.

Endergonic is a positive delta G while endothermic is a positive delta H
