Is it multiple choice? I believe it's brain, but I could be wrong.
I am confused as to what your question is specifically asking but the chemical formula for aerobic respiration is:
Oxygen + Glucose --------> Carbon Dioxide + Water
O₂ + C₆H₁₂O₆ --------> CO₂ + H₂O
Hopefully this will aid you in answering your question :)
The right answer is to measure the amount of released carbon dioxide.
The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.
A is false because glucose is not found in the urine, except in the case of diabetes mellitus.
C is false because the consumption of calories does not mean that we will directly use it.
D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.
