Glucose and fructose are measured as an indicator of sucrase activity because they are a product of it.

Explanation:

Sucrase is an enzyme which catalyzes the hydrolysis of sucrose to produce fructose and glucose.

Glucose is a simple sugar that is the main source of energy and fructose is a type of sugar that can be found in vegetables and fruits. As glucose and fructose are a product of sucrase activity, measure them is an indicator of this activity.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
