Could someone explain why this is wrong? which of the following concerning allosteric inhibitors is not true? a) can inhibit an enzyme by changing the shape of the active site b) can inhibit an enzyme by changing the shape of the enzyme c) can inhibit an enzyme by covering the active site d) all of these are not true the answer was d, but i don't understand why. i put b because it only changes the shape of the active site and not the enzyme itself, but that was wrong.

The answer is;  C

An allosteric protein does not bind to the active site of an enzyme. Only the subtrate binds the active site. However, some enzymes have an allosteric site where the allosteric protein binds and influences the conformation of the enzyme. This change in conformation on binding may facilitate or inhibit the binding of subtrate to the enzyme active site. Therefore, there are two type of allosters; inhibitors and activators.  

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
