what considerations do you need to make to ensure that your solution uses food that is most efficient for cellular respiration?

The process of cellular respiration requires optimum temperature, enzymes and oxygen supply along with the glucose as reactant which is there in the food solution. These considerations are made to ensure that the solution uses food that is most efficient for cellular respiration.

Explanation:

There are certain enzymes in the system which requires the optimum temperature to carry out their function if the temperature is too low or enzyme concentration is not appropriate the reaction will not proceed or will be very slow. Also, continuous oxygen supply is a must reactant for cellular respiration to occur.

So, it is evident that to produce energy in cellular respiration optimum temperature (37 degrees in human), the appropriate concentration of enzymes and continuous oxygen supply is required along with the glucose in the solution.

if you listed your answers right then i believe your answer is b.
