Answer :
The rate of cellular respiration may be or photosynthesis may be measured using product or reactant in the following ways :
- Quantity of oxygen : The amount of oxygen intake during cellular respiration used by cells to produce energy by the reactant.
- Quantity of carbon dioxide : During cellular respiration, carbondioxide is given off as a product. Hence, it can also be used to measure cellular respiration.
- Finally, the amount of glucose consumed may also be used to measure the rate of cellular respiration.
Hence, the rate of cellular respiration may be measured using product or reactant by ; the amount of oxygen, carbondioxide and glucose.
