Respiration Experiments Quiz

What is the purpose of using a hydrogen carbonate indicator in respiration experiments?

• To measure the temperature change

• To measure the amount of oxygen released

• To measure the amount of carbon dioxide released

• To measure the pH level

Which of the following organisms can be used to measure CO2 release in the experiment?

• Boiled seeds

• Germinating seeds

• Dried leaves

• Insects

Why is it important to control variables in the CO2 measurement experiment?

• To change the color of the indicator faster

• To decrease the amount of CO2 produced

• To increase the speed of the reaction

• To ensure the experiment is valid

What is the expected outcome when using germinating seeds in a thermos flask for the heat production experiment?

• The temperature will decrease

• The temperature will remain constant

• The temperature will increase

• The seeds will stop respiring

What type of reaction is respiration, based on the heat production experiment?

• Endothermic

• Exothermic

• Catalytic

• Neutral
