It is extremely stable. It's not possible to calculate the answer with the data given. In an organism, the energy available to do work is called free energy because a. it can be obtained with no cost to the system. Enzymes are proteins that function as catalysts. Enzymes display specificity for certain molecules to which they attach.
Enzymes provide activation energy for the reactions they catalyze.
The activity of enzymes can be regulated by factors in their immediate environment. An enzyme may be used many times over for a specific reaction. According to the second law of thermodynamics, a. the entropy of the universe is constantly increasing. They combine molecules into more complex and energy-rich molecules. They involve endergonic reactions that break complex molecules into simpler ones.
