In 3-4 sentences, explain how the rate of photosynthesis or cellular respiration can be measured using products or reactants.

The rate of photosynthesis can be measured by tracking the production of oxygen, which is a product of the reaction. By measuring the amount of oxygen released over a certain period of time, the rate of photosynthesis can be determined. Similarly, the rate of cellular respiration can be measured by monitoring the consumption of oxygen, which is a reactant in the process. By measuring the decrease in oxygen concentration, the rate of cellular respiration can be calculated.

The rate of photosynthesis can be measured by monitoring the production of oxygen (a product) or the consumption of carbon dioxide (a reactant). By collecting the amount of oxygen released or carbon dioxide consumed over a period of time, the rate of photosynthesis can be determined. Similarly, the rate of cellular respiration can be measured by monitoring the consumption of oxygen (a reactant) or the production of carbon dioxide (a product).
