Lab 5 Cellular Respiration by Kris Layher Lab 5 Cellular Respiration Introduction Cellular respiration is the procedure of changing the chemical energy of organic molecules into a type that can be used by organisms. Glucose may be oxidized completely if an adequate amount of oxygen is present.
The pressure due to C02 might cancel out any change due to the consumption of oxygen.
Essay about Lab report over cellular respiration and photosynthesis Makenzie Ann Cox October 22, Biology Lab Report Amounts of Carbon Dioxide/ Oxygen Animals are Producing/ Consuming Introduction Every cell needs a source of energy in order to perform their daily functions. This Lab Report Cellular Respiration Lab Report and other 64,+ term papers, Tell about the relation between cellular respiration, and oxidation-reduction reactions. Describe what happens to the oxidation number during this process. and place 1 piece over /5(1). 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).
To get rid of this problem, a chemical will be added that will selectively take out C Potassium hydroxide will chemically react with carbon dioxide by the following equation: Pressure changes in the respirometer are directly relative to a change in the amount of gas in the respirometer, as long as the volume and the temperature of the respirometer do not change.
To judge the consumption of oxygen in two different respirometers you must reach equilibrium in both respirometers.
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. The laws are summarized in general gas law that states: The cooler temperatures in the other water bath should cause the rate to be much slower in all three respirometers.
Materials A Water bath, thermometer, masking tape, washers, beads, germinating peas, non-germinating peas, beakers, graduated cylinder, ice, paper, and pencil are needed for this lab. Methods Begin the experiment by setting up two water baths, one at room temperature and the other at 10 degrees Celsius.
Next, find the volume of germinating peas, non- germinating peas and bead, and beads alone. Repeat these steps for another set of peas and beads. Assemble the six respirometers, placing enough KOH pellets to cover the bottoms of the respirometers.
Put non-absorbent cotton balls in each respirometer above the KOH pellets and then add the peas and beads. Place one set of respirometers in the room temperature water bath and the other set into the 10 degree water bath.
Slightly elevate the respirometers, supporting them with masking tape, for 5 minutes while they equilibrate. Record the data into the table. In this activity, you are investigating both the effect of germination versus non-germination and warm temperature versus cold temperature on respiration rate.
Germinating peas should consume more oxygen than non-germinating peas. Peas germinating at warm temperatures should consume more oxygen than peas germinating at cold temperatures.
This activity uses a number of controls. Identify at least three of the control, and describe the purpose of each control.
Water baths held at constant temperature Volume of KOH is the equal in every tube Equilibration time is identical for all respirometers 3.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). Photosynthesis and Cellular Respiration Nina R. McCray May 5, Biology Lab (SCIEA) LaDonna McCowan-Ferrier Photosynthesis and Cellular Respiration Lab Report Introduction This is an investigation of the effect of the intensity of light (photosynthesis) have on the rate of cellular respiration (measured as the number of oxygen bubbles).

Cellular respiration is the process in which most eukaryotic organisms break . 1 LAB #6 – Photosynthesis and Cellular Respiration Introduction In order to survive, organisms require a source of energy and molecular building blocks to construct all of their biological molecules.
The AP Biology Lab 5 uses respirometry techniques to calculate the rate of oxygen consumption (cellular respiration) in germinating pea seeds.
The effect of temperature and whether a seed has broken dormancy are quantified and graphed. The ideal gas law and its concepts are reviewed and applied.
