Explain preparation of glucose form sucrose

For preparation of glucose from sucrose the condition required are

Name the enzymes and write the reactions involved in the preparation of ethanol from sucrose by fermentation.

A solution is prepared by adding 360 g of glucose to 864 g of water. Calculate mole fraction of glucose (molar mass of glucose = 180).

Which enzyme is involved in the conversion of glucose to ethanol and sucrose to glucose and fructose

2g mixture of glucose and sucrose is dissolved in 1 litre water at 298K to develop osmotic pressure of 0.207 atm. Calculate percentage composition of glucose and sucrose by mole as well as by mass.

Describe laboratory method for preparation of glucose . Write the reaction that indicates the presence of - CHO group in glucose .
