What is the primary molecule for cellular respiration?

Protein
Carbohydrates
Lipids
Oxygen

The correct answer is: Carbohydrates

Carbohydrates are the primary molecule for cellular respiration because they are broken down into glucose, which is then used to produce ATP (energy) through cellular respiration. Proteins and lipids can also be broken down for energy, but they are not the primary molecules and are generally used as a secondary source. Oxygen is an essential component of cellular respiration, but it is not the primary molecule being used for energy production. Therefore, the best answer is B Carbohydrates.
