Question

1. Which of the following statements are corrects?

   		When the substrate concentration is equal to KM, the reaction rate is half of its maximal value
   		The value of KM is proportional to the concentration of the ES complex
   		Inhibitors are molecules capable of decreasing the enzyme activity
   		Uncompetitive inhibitors have no effect on Vmax

fill in the blanks

1. The respiratory chain is a set of_______complexes whose role is to transport _______ from reduced co-factors to dioxygen. The (entry from previous blank) are shuttled from complex____________ to complex _________ to complex__________ . The transfer of electrons is associated with a release of _________ which allows__________ to pass from the mitochondrial matrix into the intermembrane space. Given that the internal membrane is impermeable, an electro-chemical gradient of protons will thus form on either side of this membrane. These protons can return to the _____________by passing through ___________. The passage of protons through (entry from previous blank) will catalyze the synthesis of ________ from_______ and_______ .

Answer 1

1. The correct statement is when the substrate concentration is equal to KM, the reaction rate is half of its maximal value.
