No. Enzymes are ORGANIC catalysts. Enzymes are types of protein that are very similar to inorganic catalysts. Both increase the rate of a reaction (while decreasing activation energy.) Also, neither of them are used up or changed in the reactions that they speed up. A difference between the two is that enzymes are complex proteins but catalysts are simple inorganic molecules. The main difference is the way that the two are affected by temperature. Like other proteins, an increase in temperature causes an enzyme to denature and change shape. The shape of an enzyme is essential for its role in the reaction because it must fit with the specific substrate (the thing that it is helping to break down/speeding up the reaction of). Therefore, the enzyme will not speed up the reaction if it is denatured and no longer is the same shape. An inorganic catalyst, on the other hand, is more effective at a higher temperature and increases the reaction rate even more.
A coenzyme is a non-protein compound that binds to an enzyme to help it function properly, while a prosthetic group is a non-protein component that is permanently attached to an enzyme and is essential for its activity. In other words, coenzymes are temporary helpers, while prosthetic groups are permanent additions to the enzyme structure.
Prosthetic groups can be as simple as a single metal ion bound into the enzyme's structure, or may be a more complicated organic molecule (which might also contain a metal ion). it is permanently bonded to enzyme. Activator is only metal ion that is detachable. source:chemguide.co.uk Stuffidious.com
That enzyme is called a kinase. Kinases catalyze the transfer of a phosphate group from adenosine triphosphate (ATP) to another molecule.

No, lipids are organic molecules composed of carbon, hydrogen, and oxygen. They are a diverse group of compounds that include fats, oils, waxes, and other similar molecules. Inorganic compounds, on the other hand, do not contain carbon-hydrogen bonds.

No, a single zinc atom is not considered a prosthetic group. Prosthetic groups are non-protein components that are permanently attached to a protein and are essential for its function. Zinc ions can act as cofactors, which are required in catalyzing enzyme reactions, but they are not considered prosthetic groups on their own.
Yes! The umbrella term for coenzymes and prosthetic groups is 'cofactor' - though many internet and book sources interchange the terms. If someone says 'cofactor' they could mean either 'prosthetic group' OR 'coenzyme'. One example of a vitamin prosthetic group is vitamin B12, biotin. Like all prosthetic groups, this tightly bound molecule cannot leave its enzyme, or the enzyme shall not be able to function properly. Coenzymes on the other hand, CAN leave the enzyme it works with; it is a free molecule. Hope this helps! SOURCE: Vigourous scientific literature searches for my degree.
oxygen hydroxide - - - - - Are you doing organic or inorganic chemistry? This group has two names. Inorganic chemists call this a Hydroxide group. Organic chemists call it an Alcohol group.
That enzyme is called a kinase. Kinases catalyze the transfer of a phosphate group from adenosine triphosphate (ATP) to another molecule.
A coenzyme is a small, organic molecule that helps enzymes function by carrying chemical groups between enzymes, while a prosthetic group is a non-protein molecule covalently bound to a protein and is essential for its biological activity. In simpler terms, coenzymes are temporary helpers, while prosthetic groups are permanent attachments to proteins.
I'm no biochemist, but I believe there's a large if not complete overlap between "prosthetic group" and "coenzyme", or at least between "prosthetic group" and "cofactor". At least in the case of some dehydrogenases, FAD is covalently bound at an active site and accepts two hydrogen nuclei and two electrons to become FADH2. It then passes these to another molecule and returns to its oxidized state.
proteins
Enzyme is an organic catalyst. Enzyme is a quartenary protein, with a heme group in middle. The quaternary structure, cosistnts of 2 alpha and 2 beta chains.
