Sort each of the following descriptions into the most appropriate bin based on whether it accurately describes a cofactor, a coenzyme, or a prosthetic group. (Not every answer may be used.)

- the heme group of catalase is an example of one of these

- a small molecule that an enzyme requires to function; can be amino-acid based, a metal, or an organic compound

- a metal, such as iron, that is not permanently associated with an enzyme may be an example of one of these

- a coenzyme that is permanently associated with an enzyme

- it is usually derived from vitamins

- a cofactor that has an organic component, but no amino acids

a small molecule that an enzyme requires to function; can be a metal or an organic compound

(1) It is known as a prosthetic group as heme consist of a protoporphyrin ring and a central iron atom. A prosthetic group is a specific non-polypeptide unit which is required for some protein's biological function.

(2) Coenzyme.

(3) It is known as an example of a cofactor as it is not a permanent part of the enzyme.

(4) It is known as a prosthetic group as it is permanently attached to the enzyme.

(5) Coenzyme-A.

(6) Cofactor.

(7) Cofactor.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.
