What does niacin act as in enzyme-catalyzed reactions?
coenzyme
The reactants of enzyme - catalyzed reactions are known as?
Substrates
Difference between homogeneous and heterogeneous catalysis?
Homogeneous catalysis is used over heterogeneous for the following reasons 1)There are more complicated catalytical sites (chemically and geometrically) which gives improved selectivity to a certain product 2) The catalysts are usually in solution and so access to the reagents is easier so there is improved activity and milder reaction conditions can be used. 3) Another advantage of the catalysts being in solution is that the heat transfer for highly exothermic or endothermic reactions is not a problem 4)Mechanisms are better understood. Advantage of heterogeneous catalysis is that the catalyst is usually solid and therefore is easier to extract and recycle.
Is 16 karat gold homogeneous or heterogeneous?
Homogeneous; you cannot separate it without chemical reactions and no one area of the gold looks different than another.
Rank reactions from fastest to lowest uncatalyzed reaction reaction catalyzed by enzyme A reaction catalyzed by enzyme B?
A reaction catalyzed by enzyme a reaction cataly by enzyme b uncatalyzed reaction
Why is homogeneous and heterogeneous important?
Homogeneous and heterogeneous reactions are important in catalysis and oxidation coupling of methane over chloride.

What kind of chemical reactions speed up enzyme catalysis?
This varies per enzyme and what it catalyzes but chemical reactions that result in an increase in temperature often speed up enzyme catalysis.
During enzyme-catalyzed reactions strate is synonym for?
Reactant.
What are Enzyme-catalyzed reaction?
