All enzymes are protein molecules
A nonprotein organic molecule loosely associated with an enzyme is known as a coenzyme. Coenzymes assist enzymes in catalyzing reactions by acting as carriers for chemical groups or electrons. They often derive from vitamins and are essential for the proper functioning of many enzymes. Unlike substrates, coenzymes are not permanently bound to the enzyme and can participate in multiple reactions.
Lactose is a carbohydrate and is an organic compound.
An enzyme is a protein and has many carbon hydrogen bonds, so it is an organic molecule.

The lock and key hypothesis explains enzyme functioning. It suggests that enzymes and substrates fit together like a lock and key, with specific enzyme-active sites binding to specific substrates to catalyze reactions.
A nonprotein compound that combines with an inactive enzyme to form an active enzyme system.
A nonprotein compound that combines with an inactive enzyme to form an active enzyme system.

Cofactors are nonprotein additions that are needed for enzyme activity. Cofactors are derived from vitamins and minerals.
Lactose is a carbohydrate and is an organic compound.
A critical component of the glutathione peroxidase antioxidant enzyme system is selenium, an essential trace element that serves as a cofactor for the enzyme. Glutathione peroxidase catalyzes the reduction of hydrogen peroxide and lipid peroxides, protecting cells from oxidative damage. The presence of selenium is vital for the proper functioning of this enzyme, as it is incorporated into the enzyme's active site in the form of selenocysteine. This highlights the importance of selenium in maintaining cellular health and antioxidant defense.
A holoenzyme consists of both a protein component, known as the apoenzyme, and a non-protein component, known as the cofactor or coenzyme. The cofactor can be a metal ion or a small organic molecule that is necessary for the enzyme's activity. Together, the apoenzyme and cofactor form the functional holoenzyme.
An enzyme is a protein and has many carbon hydrogen bonds, so it is an organic molecule.
Yes, an enzyme is an organic substance, because it is a protein, and all proteins contain carbon, which is the definition of an organic substance.
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.
Yes.
