Question

What is cofactor and coenzyme?

Answer 1

Please interpret the second bullet point for me

Answer 2

So you asking What is cofactor and coenzyme?

Answer 3

The second bullet point says
Can be:
-Inorganic cofactors
-Organic coenzymes

Answer 4

yes

Answer 5

my notes have no definition for coenzyme and cofactor and all it says is what it "can be"

Answer 6

what is cofactor, coenzyme and the relation between the two? does one of them produce the other?

Answer 7

Metal ions are usually cofactors. Coenzymes are a specific type of helper or partner that are organic molecules required for enzyme function that bind loosely to an enzyme. They are often, though not always, derived from vitamins. Prosthetic groups are enzyme partner molecules that bind tightly to an enzyme.

Does this help?

Answer 8

I haven't heard that they're made of metal ions. perhaps i havent gone that far yet

Answer 9

but im more confused as to what my professor meant by the second bullet point

Answer 10

it doesn't really tell me anything about what coenzymes are at the least..

Answer 11

Coenzymes are small molecules. They cannot by themselves catalyze a reaction but they can help enzymes to do so. In technical terms, coenzymes are organic nonprotein molecules that bind with the protein molecule (apoenzyme) to form the active enzyme (holoenzyme). ~

Answer 12

are cofactors always inorganic then?

Answer 13

Cofactors can be subdivided into either one or more inorganic ions.

Answer 14

oh okay thanks

Answer 15

You're Welcome :))

Answer 16

^ smart

Answer 17

Google has more to say about them

A Coenzyme is a small organic non-protein MOLECULE that carries chemical groups between enzymes while a

COFactor is a non-protein CHEMICAL COMPOUND that is bound tightly to an enzyme and is required for catalysis.

A cofactor is a non-protein chemical compound that is required for the protein's biological activity. These proteins are commonly enzymes, and cofactors can be considered "helper molecules" that assist in biochemical transformations.

Good luck
