the answer you are looking for is B. Glucose is broken down into two pyruvate molecules.
this process occurs during glycolysis
 
        
             
        
        
        
Without using the scientific method, it would be much harder to determine a factor that could cause your experiment to fail. By sticking to only one of the methods you could easily destroy your experiment without the background search needed or the materials planned out.

Answer:
The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual
Explanation:
In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).
 
        
             
        
        
        
Because we all came from two people bible wise. Evolution wise, same thing kinda. We all came from the same person in the beginning.
