[Q]: Question: Azidothymidine (AZT) used against the human immunodeficiency virus:
Options: <1> It binds to the cellular RNA polymerase and blocks transcription. <2> It binds to the early promoter of the virus and prevents its recognition by RNA polymerase. <3> Antagonizes the phosphorylation of nucleosides, thus inhibiting the synthesis of viral DNA. <4> Blocks the transport of thymidine to the cellular interior. <5> Inhibits transcriptase
[A]: 5

[Q]: Question: According to the Arrhenius equation (k = A e-Ea / RT):
Options: <1> The speed of a reaction is directly proportional to the temperature. <2> A high activation energy implies that the speed constant depends markedly on the temperature. <3> The pre-exponential factor or frequency factor (A) is dimensionless. <4> The activation energy depends on the temperature. <5> The activation energy is always negative.
