Question 1
Which of the following statements about enzymes is incorrect?
◦
They are proteins that catalyze specific biologic reactions.◦
Several hundred are now known.◦
The molecules they react with are called substrates.◦
They are equal to inorganic catalysts in efficiency.◦
All of these are correct.Question 2
Which of the following statements best describes the condition(s) needed for a successful formation of a product according to the collision model?
◦
The collision must involve a sufficient amount of energy, provided from the motion of the particles, to overcome the activation energy.◦
The relative orientation of the particles has little or no effect on the formation of the product.◦
The relative orientation of the particles has an effect only if the kinetic energy of the particles is below some minimum value.◦
The relative orientation of the particles must allow for formation of the new bonds in the product.◦
The energy of the incoming particles must be above a certain minimum value, and the relative orientation of the particles must allow for formation of new bonds in the product.
