Next, refill the graduated cylinder with 50 mL of water and drop 25 non-germinating peas into it. If you used the same experimental design to compare the rates of respiration of a 25 g reptile and a 25 g mammal, at degrees Celsius, what results would you expect?

In this lab, the volume of O2 consumed by germinating and non-germinating peas at two different temperatures will be measured. Production of CO2 how many moles of CO2 are produced in cellular respiration? Complete the following table: Check the temperature in both baths and record in table 5.

Glucose may be oxidized completely if an adequate amount of oxygen is present. Allow the respirometers to equilibrate for three more minutes and then Bio 156 lab report the initial water in each pipette time 0.

R is the gas constant.

Vials 4, 5, and 6 should be in the bath containing water that is 10oC. Then place a small wad of dry cotton on top of the KOH-soaked absorbent cotton.

What is the purpose of KOH in this experiment? A number of physical laws relating to gases are important to the understanding of how the equipment that you will use in this exercise works. Make sure to use about the same amount of cotton in each vial. The vials should not be shifted during the experiment and your hands should not be placed in the water during the experiment.

Why is it necessary to correct the readings from the peas with the readings from the beads? During respiration, oxygen will be consumed and its volume will be reduced to a solid.

Peas germinating at warm temperatures should consume more oxygen than peas germinating at cold temperatures. Explain why water moved into the respirometer pipettes. To obtain a temperature of 10oC add ice to of the baths until the temperature in the bath is 10oC.

Slightly elevate the respirometers, supporting them with masking tape, for 5 minutes while they equilibrate. This activity uses a number of controls.

Next, refill the graduated cylinder with 50 mL of water. Water baths held at constant temperature Volume of KOH is the equal in every tube Equilibration time is identical for all respirometers 3.

Lab 5 Cellular Respiration by Kris Layher

They will be used in respirometer 3. Then remove these peas and place them on a paper towel.

T is the temperature of the gas in degrees K. While the peas underwent cellular respiration, they consumed oxygen and released carbon dioxide.

If temperature and pressure are kept constant then the volume of the gas is directly proportional to the number of molecules of the gas. To show the actual rate at which cellular respiration occurs in the peas. If it does not stop, there is a leak. Carbon dioxide is removed so the change in the volume of gas in the respirometer will be directly proportional to the amount of oxygen that is consumed.Bio Lab Report.
