Ap bio question. thank you for helping = )?

im starting ap bio next year. and i have a question i dont know.





1. which molecules bind to the active site of an enzyme?


a. substrate


c. allosteric inhibitor


b. allostaric activator


d. noncompetitive inhibitor


e. b and c





here is another... sometimes the questions are soo easy that they seem like a trick question. = )


Before a controlled experiment can be conducted all the following must be completed EXECPT:


a. form a hypothesis


b. research the problem


c. define the problem


d. analyze the data





ok, well thank you all for your help = )

Ap bio question. thank you for helping = )?
1. A.


A substrate binds to the active site of an enzyme...this interaction brings the activation energy required for the enzyme to perform it's function to a lower degree.


---b. is wrong b/c an allosteric inhibitor binds to an enzyme in a spot other than the active site....an allosteric inhibitor is a noncompetetive inhibitor since it does not block the enzymes active site. Allosteric inhibitors and activators may change the affinity of the substrate for the enzyme, but the allosteric inhibitors/activators do not bind to the active site.


----d. is wrong b/c a noncompetetive inhibitor doesn't compete with the substrate since the noncompetetive inhibitor does not bind to the active site.





SO, FOR QUESTION 1, A IS DEFINITELY CORRECT.





2. D. is the correct answer. The purpose of completing a controlled experiment is to produce data, therefore, data cannot be analyzed until after the experiment has been conducted.


-a hypothesis must be formed in order to determine what data is expected from the experiment, the research problem must also be researched before starting the experiment in order to guide researchers in the proper direction. And of course, the problem must be defined or else there is no experiment to be conducted in the first place.
