Answer:
In the reaction from 6C to 5C, the released carbon takes the form of a carbon dioxide (CO2) molecule. This reaction is referring to the process of decarboxylation, in which a carboxyl group (COOH) is removed from a molecule, usually through the removal of a carbon atom as CO2.
Step-by-step explanation:
Decarboxylation is an important biochemical process that occurs in various metabolic pathways, including the Krebs cycle (also known as the citric acid cycle) and in the production of neurotransmitters such as dopamine and serotonin.
