What is the function of an enzyme cofactor?

Enzyme cofactors serve a crucial role in assisting enzyme activity, enhancing their catalytic abilities. These cofactors can be organic molecules, known as coenzymes, or inorganic elements such as metal ions. Metal ions like zinc, magnesium, and iron often help stabilize the enzyme structure or participate in the enzymatic reaction by facilitating the binding of substrates or assisting in the reaction's chemical process.

By providing structural support or participating in the reaction mechanism, cofactors are essential for the proper functioning of many enzymes. Some enzymes would be inactive without their cofactors, highlighting their importance in biochemical pathways and reactions. This functional relationship underscores the necessity of cofactors in promoting efficient enzyme activity and ensuring that biochemical reactions proceed effectively.
