Mealworms and cellular respiration lab report

In this experiment, we wanted to find out what would cause a faster or slower rate of respiration in an animal. We also successfully determined the effect of at least one factor, sound, on the rate of cellular respiration. October 30, Cellular Respiration in Mealworms Energy is at the heart of life.

Water baths held at constant temperature Volume of KOH is the equal in every tube Equilibration time is identical for all respirometers 3.

Cellular Respiration in Mealworms

For future research, we would definitely like to measure the impact of other factors, such as temperature or time of day, on cellular respiration using a similar method, and repeat the experiment on bigger, more complex organisms as well.

Can cover up the transparent holes so that in darkness, there will be no other sources of light and that in bright light, the only source of light will be the bright light. We also predicted that a higher frequency sound would cause a faster rate of cellular respiration, and through our results, this turned out to be true as well.

Yellow — high pitch. Data Analysis What did you observe and give reasons to your observations. Cells produce ATP through a process known as cellular respiration. For future research, we would definitely like to measure the impact of other factors, such as temperature or time of day, on cellular respiration using a similar method, and repeat the experiment on bigger, more complex organisms as well.

The three stages of cellular respiration are: Respiration rates were recorded in both the control group no ethanol and the experimental group ethanol.

What results would you expect. If the carbon dioxide increases steadily, we know the cells are respirating, but if the carbon dioxide is leveling off, then we know that no cellular respiration is occurring.

Using crickets or another bigger organism would also be something that we could do in the future to get a broader perspective on cellular respiration. Respiration occurred at a faster rate in the respirometers in the warm water bath. Basically, we concluded that our hypothesis was correct and that using outside factors do affect the rates of respirations on organisms.

From collecting data by placing 2 mealworms in a jar with a carbon dioxide sensor on top and connecting it to the Vernier app, we were able to find that compared to a control group where there was no sound playing, a sound with even a lower frequency still makes an impact in the rate of respiration.

Ethanol is generally known to have depressant effects on the central nervous system. Next, for the experimental cases, we again took the jar and placed two new, but identically sized mealworms we had to air out the first two and repeated the process of measuring carbon dioxide concentration over ten minutes.

Data regarding the change in carbon dioxide levels were plotted and compared using the Vernier Graphical App. The filter paper was inserted into the flask with the mealworms. We could then use the information from the graph to determine the number of moles of glucose oxidized in the ten minutes to finally obtain a quantitative rate of respiration.

Materials and Methods The materials used in this experiment were: More scientifically, it is a three-step pathway that produces ATP adenosine triphosphate.

In the lab, CO2 made during cellular respiration was removed by the potassium hydroxide (KOH) and created potassium carbonate (K2CO3). It was necessary that the carbon dioxide be removed so that the change in the volume of gas in the respirometer was directly proportional to /5(3).

The purpose of this lab was to design and perform our own experiment using organisms and manipulating specific factors of their environment (in our case the surrounding temperature) to increase or decrease the rate of cellular respiration in the worms.

Jul 11,  · Entry 6 – Mealworms Investigation Lab Report! Posted on July 11, by emilyzhao99 This is my lab report as a follow up to my previous mealworm investigation (Entry 5!). Introduction The purpose of this experiment was to study the effects of ethanol on the cellular respiration of mealworms.

Cellular respiration is the process by which cells harvest the energy stored in food. It is the intake of oxygen and energy in the form of glucose, and the cells ability to break it down into [ ].

The effect of increasing temperature on cellular respiration of mealworms 11 metabolic state and is positively correlated with the rate of the metabolic processes particularly with that of the cellular respiration.
