QUESTIONS AND CORRECT ANSWERS
How will the rate of a catalyzed reaction be affected if the solid catalyst is finely ground
before it is added to the reaction mixture? - CORRECT ANSWER The rate will be
faster because a greater surface area of catalyst will be exposed.
Which of the following most likely will occur if a homogeneous catalyst CANNOT be

The production of a variety of opsins functions to:
A.increase sensitivity to low light.
B.enable the detection of different colors.
C.ensure fast recovery of 11-cis-retinal after exposure.
D.increase refractive index of the eye lens. - CORRECT ANSWER The wavelength of
light absorbed by a molecule depends on its structure, and so the production of a variety of
structurally related opsins functions to enable the detection of different colors.
