Like a waterfall that does not fall because the river level is as high as the lake, just so, at equilibrium, life ceases because reaction products back up and a quick and certain death ensues. Write a short paragraph that explains HOW an enzyme works. As a biological catalyst, an enzyme speeds the rate of a reaction by lowering the energy of activation so that more of the reactants available can be turned into product. As soon as the reaction is done, the resulting product no longer has an affinity for the active site and it leaves. Now the enzyme changes back to its origional conformation and is ready for another catalytic cycle.
Cofactors are any non protein molecules that give an enzyme functionality.
If those cofactors are organic, then they are known as coenzymes. Distinguish between feedback inhibition and competitive inhibition. This inhibition is usually done by allosteric effectors. However, if the product happens to fit the active site of enzyme A, then its presence in the active site, besides being feedback inhibition, is also known as competitive inhibition.
