The rate of photosynthesis can be measured by measuring the production of oxygen gas, a product of the reaction. This can be done by collecting the gas released by a plant and measuring its volume over a certain period of time. Similarly, the rate of cellular respiration can be measured by measuring the consumption of oxygen gas, a reactant of the reaction. This can be done by measuring the decrease in the volume of oxygen gas in a closed system over a certain period of time.
A substance is dissolved in water, and the temperature of the surroundings decreases. Is this process exothermic or endothermic? Explain your reasoning in 3-5 sentences. (4 points)
The rate of photosynthesis can be measured by monitoring the production of oxygen and the consumption of carbon dioxide. This can be done using a gas exchange system where the oxygen and carbon dioxide levels are continuously measured. The rate of cellular respiration can be measured by monitoring the consumption of oxygen and production of carbon dioxide. This can also be done using a gas exchange system, where the levels of oxygen and carbon dioxide are monitored over time.
The rate of photosynthesis can be measured by monitoring the production or consumption of reactants or products. For example, the amount of oxygen gas released or carbon dioxide consumed during photosynthesis can be measured using gas sensors. Similarly, the rate of cellular respiration can be measured by monitoring the consumption of glucose or the production of carbon dioxide. By quantifying the changes in reactants or products over a specific period of time, we can determine the rate of these metabolic processes.
