Researchers use radioisotopes to study the metabolism of plants. This would then be followed by fractionation to

determine which biomolecules accumulated the radioisotopes. If a plant were exposed to 13cO2 over a long period,

where would the 13C ultimately be found?

CO2 is not stored by photosynthetic plants, so 13C would not accumulate.

O It would be found in fats/lipids, because they are used as the energy storage molecule for plants.

O All biomolecules would include 13C as a result of metabolic processes after photosynthesis.

O It would be found in carbohydrates like starch, because they are used as the energy storage molecule for plants.

Answer:

It would be found in carbohydrates like starch, because they are used as the energy storage molecule for plants.

Explanation:

The process of photosynthesis can be represented by the following chemical equation;

6CO2 + 6H2O → C6H12O6 + 6O2.

So, if the carbon atom in CO2 is labelled with 13C, the 13C will appear in the glucose which is ultimately converted to carbohydrates- the energy molecules stored in plants. A typical example of a carbohydrate is starch.

Answer:

B

Explanation:

PLANTS GET C02 FROM AIR ANDF THEN CONVERT INTO ORGANIC MATTER
