Coenzymes are organic compounds required by many enzymes for catalytic activity. They are often vitamins, or derivatives of vitamins. Sometimes they can act as catalysts in the absence of enzymes, but they aren't as effective.
Definition of Coenzymes
???? A complex organic molecule which helps certain enzymes to function correctly. It is a small molecule (not a protein but sometimes a vitamin) essential for the activity of some enzymes.
A coenzyme is a molecule that aids the function of an enzyme.
They work by transferring a chemical group from one molecule to another.
- NADP is used in photosynthesis. NADP transfers hydrogen from one molecule to another one.
- This means it can reduce (give hydrogen to), or oxidise (take hydrogen from) a molecule
