41. False.
Explanation: Adding more enzyme will increases the rate of reaction while adding more substrate (with given amount of enzyme) will increase the rate of reaction but reach to limiting rate - substrate concentration beyond this limit will not increase the rate of reaction further due to saturated active sites of enzymes.
42. True
Explanation: In noncompetitive inhibition, an inhibitor molecule binds to an allosteric site of an enzyme i.e. the site on enzyme other than the active site. Whereas, in competitive inhibition, inhibitor competes with substrate for same active site of enzyme. Therefore, noncompetitive inhibition is more effective in inhibition.

Question 1 2 pts How does a noncompetitive inhibitor decrease the rate of an enzyme-catalyzed reaction? by decreasing the free-energy change of the reaction catalyzed by the enzyme by binding to an allosteric site, thus changing the shape of the active site of the enzyme by binding to the active site of the enzyme, thus preventing binding of the normal substrate by binding to the substrate, thus changing its shape so that it no longer binds to the active site...
