Enzyme catalysis is the increase in the rate of a chemical reaction by the active
site of a protein. The protein catalyst (enzyme) may be part of a multi-subunit ...
A fundamental task of proteins is to act as enzymes—catalysts that increase the
rate of virtually all the chemical reactions within cells. Although RNAs are ...
Enzymes and chemical catalysts both affect the rate but not the equilibrium
constant of a chemical reaction. Reactions proceed downhill energetically, in
Let's explore what enzymes are, and how they can affect a reaction. The most
important affect you need to know is its ability to "catalyze" the reaction. By Ross ...
are proteins that participate in cellular metabolic processes with the ability to enhance the rate of reaction between biomolecules. Many enzymes
catalyze reactions without help, but some require an additional non-protein component called a co-factor. Co-facto... More »
What's the difference between Catalyst and Enzyme? Enzymes and catalysts
both affect the rate of a reaction. In fact, all known enzymes are catalysts, but not
Red blood cells contain the protein hemoglobin which has heme (the oxygen
carrier in our blood) as a prosthetic group. Many of the vitamins are coenzymes.
