Question

​ Humans constantly exhale carbon dioxide. Usually, this carbon originates in the atmosphere and then is incorporated into living systems. For the first part of this question, address how this atmospheric carbon became incorporated into an organism and indicate what molecule the atoms of carbon dioxide were incorporated into in the organism.​Your answer should include the formula for the reaction, a short description (2 sentences) of the two parts of this process, the specific location(s) within the organelle where these reactions occur, and, finally, indicate whether the reaction is endergonic or exergonic and identify the energy source for this process.

At some point the molecule produced in the reaction above was ingested by an organism and broken down into carbon dioxide. ​How did this occur? Your answer should include the formula for the reaction, a short description (2 sentences) of the parts of this process, the specific location(s) within the organelle where these reactions occur, and, finally, indicate whether the reaction is endergonic or exergonic and identify the energy source for this process.
