B) The enzyme has active sites where the substrate binds with the enzyme to form a complex. When the substrate binds to the active site, an induced fit is formed where the enzyme changes its shape in order to better serve the substrate and lower the activation energy of the reaction
The correct answer is the fourth option. The magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x is equal to 50x. Magnification is equivalent to the product of the objective power and the ocular lens. Ten times five is fifty.
