What will happen to the reaction if you add a certain inhibitor or activator to the substrate having allosteric enzyme set up?
A. Activator binds to active site to initiate the reaction.
B. Activator binds to regulatory site to activate the reaction.
C. Inhibitor binds to active site to speed up the reaction.
D. Inhibitor binds to regulatory site to increase rate of reaction.
Sleeping sickness is transmitted by
A. eating contaminated food.
B. droplet infection.
C. biting of tsetse flies.
D. sexual intercourse.
Answer (2)
Allosteric enzymes can be regulated by activators and inhibitors . Activators enhance enzymatic activity by binding to regulatory sites, while inhibitors generally reduce activity and can either block the active site or bind at regulatory sites. Sleeping sickness is transmitted specifically through tsetse fly bites. ;
An activator enhances enzyme activity by binding to the regulatory site, making option B the correct choice. Sleeping sickness is transmitted specifically through the bite of tsetse flies, making option C the correct answer. Thus, activators and inhibitors play crucial roles in enzyme regulation and understanding how diseases like sleeping sickness transmit is important for public health.
