I need some help with school work

I need a little help with some questions in lab for biology class. They are:

1. One source of hydrogen peroxide in the human body?
2. In which organelle in the cell is catalase found?
3. Assume that the quantity of enzyme used to catalyze the reaction is cut in half. What effect will this have on the total volume of gas envolved?
4. Do all enzymes behave in a similar manner?!

1. White cells
2. Lysosomes
3. No effect, but the reaction time will be cut in half
4. Yes, they all accelerate reactions by fitting "keys" and "locks"
together, that is by matching reactants.
