What is the independent variable for the cellular respiration experiment?
The independent variable is the type of peas (Germinated or Nongerminated) and the temperature (Room or Cold Temperature). The dependent variable is the consumption of oxygen from all 6 respirometers. The control group is respirometer three from both temperatures that consists of only glass beads.
What is the aim of aerobic respiration experiment?
All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. In this experiment, the rate of cellular respiration will be measured by monitoring the consumption of oxygen gas.
How do you investigate aerobic respiration?
Investigating respiration
- Respiration by living organisms can be investigated by carrying out experiments to show the production of carbon dioxide and heat.
- Limewater can be used to detect carbon dioxide.
- Breathing in through the mouthpiece draws air from the atmosphere in through tube A.
What two independent variables were tested in the respirometer?
What two independent variables were tested in the respirometer (pea) experiment.
What is are the dependent variable s in the respiration experiment?
For the dependent variable, you will measure the circumference of a balloon that has been placed over your fermentation flask. The dependent variable is the one that you measure to determine the influence of the independent variable on your different treatments.
What gas is used in respiration experiment?
carbon dioxide gas
The carbon dioxide gas produced by respiration goes out into the air.
What is the role of sugar in yeast experiment?
Yeast can use oxygen to release the energy from sugar (like you can) in the process called “respiration”. So, the more sugar there is, the more active the yeast will be and the faster its growth (up to a certain point – even yeast cannot grow in very strong sugar – such as honey).
What is the word equation for aerobic respiration in humans?
Glucose + Oxygen → Energy + Carbon dioxide + Water.
How would you demonstrate that oxygen is used up during aerobic respiration?
Aerobic respiration utilizes oxygen present in the cells. For example, If a person is performing strenuous physical activities, then the oxygen in the cells gets used up at a much faster rate, thereby, causing oxygen deficiency in the cells because almost entire oxygen was utilized.
How do you do photosynthesis experiment?
Use a measuring spoon to scoop out 1/8 teaspoon of baking soda, and fill your measuring cup with 300 milliliters of water. Mix the baking soda into the water to create your bicarbonate solution. When the baking soda dissolves in the water, it releases carbon dioxide. This will be used by the spinach for photosynthesis.
