Jeannie Kopstein November 2014 AP Biology Respiration lab write up Mrs. Beck Background: Aerobic cellular respiration is a pivotal process in which organisms carry out in order to sustain life. It is characterized by the release of energy from organic compounds by means of chemical oxidation within the mitochondria of the cell. The reactants are glucose and oxygen‚ and after a series of complex steps‚ the products of carbon dioxide‚ water‚ and ATP + heat are released. Thus

BIG IDEA 2 6 EDVO-Kit: AP06 Cellular Respiration See Page 3 for storage instructions. EXPERIMENT OBJECTIVE: The objective of this experiment is to apply the gas laws to the function of the respirometer. Students will observe cell respiration of germinating and non-germinating seeds and describe the effects of temperature on the rate of cell respiration.

seeds. This is because germinating seeds were growing and needed oxygen to produce ATP and continue to grow. The purpose of this was to see the difference in respiration rates of non-germinating seeds and germinating seeds.We did this by using respirometers. This is a device that measures the rate of respiration of a living organism by measuring the rate of exchange of oxygen and/or carbon dioxide. It is composed of a vile that contains the peas and air‚ the vial is sealed with a rubber stopper and

Title: Amount of Oxygen‚ Mung Beans (Vigna Radiata) Consume during Cellular Respiration Introduction: Cellular respiration is a catabolic reaction that refers to the process of converting chemical energy of organic molecules into a simplify form so it can be used immediately by organism. Glucose may be oxidized completely if sufficient oxygen is available‚ by the following equation: C6H12O6 + 36 ADP + 36Pi + 6O2(g) 6 H2O + 6 CO2(g) + 38 ATP + heat All organisms‚ including plants and animals

Analysis: In this lab we measured the rate of respiration of germinating mung beans and germinating peas at room temperature and 10 degrees Celsius. The rates of respiration at room temperature were higher than the rates of respiration in cold water. The reaction rate of the germinating peas at room temperature was .0125 ml/min and the reaction rate of the peas at 10 degrees Celsius was .0095 ml/min. The same is true for the germinating mung beans. At room temperature the rate of reaction was .0105

The procedures are simple‚ after connecting the hydraulics bench outlet to the test set‚ the pump is started. Then adjust the flow rate to 10‚ 15‚ 20 L per minute. The flow rate and readings for each manometer should be taken and recorded in the table provided. The total head at any point is indicated on
