question 77

Multiple Choice

Figure 6.2 Rate of an enzyme-catalyzed reaction as a function of varying reactant concentration, with the concentration of enzyme held constant.
-In Figure 6.2, why does the reaction rate plateau at higher reactant concentrations?

• A) Feedback inhibition by product occurs at high reactant concentrations.
• B) Most enzyme molecules are occupied by substrate at high reactant concentrations.
• C) The reaction nears equilibrium at high reactant concentrations.
• D) The activation energy for the reaction increases with reactant concentration.
• E) The rate of the reverse reaction increases with reactant concentration.

Definitions:

Promoter Regions

Specific DNA sequences where RNA polymerase binds to initiate transcription of genes.

Operator

In genetics, a segment of DNA to which a repressor binds, controlling the expression of genes; in mathematics, a function or symbol that represents a function from a set of numbers.

Polyadenylation

That part of eukaryotic mRNA processing in which multiple adenine-containing nucleotides (a poly-A tail) are added to the 3' end of the molecule.

Prokaryotic mRNA

Messenger RNA found in prokaryotic organisms that is used to carry genetic information from DNA for protein synthesis.
