Question

Where do you think the carbon dioxide used in the formation of urea comes from? Where does the remainder of excess carbon dioxide go to be excreted?​

Answer 1

Answer:

As large quantities of carbon dioxide are produced during the ammonia manufacturing process as a byproduct from hydrocarbons (predominantly natural gas, less often petroleum derivatives), or occasionally from coal (steam shift reaction), urea production plants are almost always located adjacent to the site

Explanation:

The step of the urea cycle involving the incorporation of carbon dioxide takes place in the mitochondrion, which is also the site of the Krebs cycle, which generates CO 2 by oxidation of carbon-containing metabolites (specifically, by oxidative decarboxylation of carboxylic acids). Thus, the mitochondrion has the highest CO 2 concentration to be found anywhere in the organism (under normal conditions) and is the perfect place for a reaction that uses CO 2 as a reactant. (The reaction also requires ATP, which is also generated in the mitochondrion.)

Answer 2

The carbon dioxide used in the formation of urea comes from mitochondria.

• The urea is formed in the hepatocytes of the liver.
• It is later released into the bloodstream.
• The cycle of urea is basically a biochemical reaction that is produced from ammonia.
• Further, the kidney filters the urea through the process of urination.
• The remainder of excess carbon dioxide is excreted through the process of exhalation.
