Question

Match the following together:

Urobilinogen and Urobilin
Oxidized form and Reduced Form
a) Urobilinogen - Reduced Form, Urobilin - Oxidized Form
b) Urobilinogen - Oxidized Form, Urobilin - Reduced Form
c) Urobilinogen - Reduced Form, Urobilin - Reduced Form
d) Urobilinogen - Oxidized Form, Urobilin - Oxidized Form

Answer 1

Urobilinogen is the reduced form while Urobilin is the oxidized form, hence the correct option is a) Urobilinogen - Reduced Form, Urobilin - Oxidized Form.

Step-by-step explanation:

To match the following together: Urobilinogen and Urobilin are two different compounds related to the heme breakdown pathway in the body. Urobilinogen is the reduced form of bilirubin, which is created in the intestines by bacteria acting on bilirubin. It can either be excreted in the feces or further processed in the kidneys. Urobilin is the oxidized form of urobilinogen and is typically found in urine, giving it its characteristic yellow color. So the correct answer is:

a) Urobilinogen - Reduced Form, Urobilin - Oxidized Form

In terms of biochemical principles, an oxidized substance tends to lose electrons, while a reduced substance gains or has a higher number of electrons. This concept relates to redox (oxidation-reduction) reactions, which are processes that are fundamental in metabolic pathways, including those that involve heme and its breakdown products.
