Answer:
The correct answer is - yes lactase action is exergonic.
Step-by-step explanation:
Lactase is an enzyme located in the small intestine of mammals including humans, however it is produced by many organisms in their body. Lactase is an essential enzyme as it helps in the digestion of the whole milk by breaking down the lactose, sugar present in milk.
Exergonic reactions are the reaction that releases energy by the breaking of molecules in any reaction. Generally, catabolic reactions are exergonic lie lactase catabolizes the lactose present in milk and release energy.
Thus, the correct answer is - yes lactase action is exergonic.
