Enzyme and ATP help
I'm new to this forum. I am currently taking biology correspondence and am having troubles with a couple questions.
Lacatse hydrolyzes lactose into glucose and galactose. Galactose is then converted to another glucose by galactosidase. Outline the reaction involving these enzymes using a word equation.
I initially thought:
LactASE + H2o -> glucose and fructose
and had no clue for the second part.
Then I looked on the net and found these 2 equations:
Lactose + H2O ----------> galactose + glucose
Galactose + O2 --------------> galactohexodialdose + H2O2
Are these 2 equations about something totally different?
Also, I am not sure about this question:
How does the structure of ATP make it an effective energy carrier? Where does the energy stored in the molecules come from and how is it released?
The biology course is for the last year in highschool, so please bare with me and not make explanations to complicated.
Your help is greatly appreciated.

An ATP synthase (EC 22.214.171.124) is a general term for an enzyme that can synthesize adenosine triphosphate (ATP) from adenosine diphosphate (ADP) and inorganic phosphate by utilizing some form of energy.
The overall reaction sequence is:
ADP + Pi → ATP

These enzymes are of crucial importance in almost all organisms, because ATP is the common "energy currency" of cells.
