Answer:
The labeled Cabon will be present in carbohydrate of organism in the culture labelled with CO2.
Explanation:
Organism with ability to produce their own foods as complex organic subtance, from simple inorganinc form are called Autotroph.They do not depend on other organins for survivals.Rather they make use of sunlight as source of energy as in photosynthensis, or byproducts of some inorganic chemical reactions as in Chemosynthesis.
In this scenario, the researcher was investigating photosynthesis.
the first step in photosynthesis is the splitting of water molecules to; H+ , e-and O2, during light dependent stage.This is photolysis of water.
the second stage which is light independent stage, involved the reduction of the C02 by H+ in Calvin Cycle to form carbohydrate as C6H12O6.
Therefore, if the organism happens to be an autotrophs it should reduces the labelled CO2 to glucose as C6H1206, Therefore labelled Carbon of C02 must be present in the carbohydrate of the organism.Autotrops makes use of inorganic molecules to synthesize their foods. CO2 is inorganic. This further prove that the labeled C of CO2 must be present in the CHO of the organism.
