Enzymes work by bringing reactants together at a LOWER energy level than they would need in an uncatalysed reaction.

Explanation:

Catalysts decreases the activation energy for a reaction causing the reaction to occur at a faster rate. Thus enzymes accelerates reactions rate by decreasing the activation energy.

Immediately an enzyme is brought into the reaction, the enzyme attaches itself to the substrate to produce a complex called an enzyme/substrate complex (ES) which in turn reduces the activation energy, and speeding up the rate of reaction. A enzyme/product complex (EP). Is fotmed in the process.

lysosome is this part of the cell is surrounded by a very thick outer membrane to protect the rest of the cell from its strong enzymes.

i believe the answer would be b. hope it : )
