Colleen Hamilton AP Lab 4: Determining the Rate of Cellular Respiration of Peas at Varying Temperatures and Stages of Germination I. Purpose and Intro The purpose of this lab is to determine the rate at which germinating peas respirate at varying temperatures and stages of germination. Cellular respiration is the set of metabolic reactions and processes that takes place in an organism’s cells in order to create ATP from sugar. It occurs in the mitochondria and comprises three stages: glycolysis

Cellular Respiration In this lab the effects of different substrates on the rate of cellular respiration is being put to a test which is a very interesting experiment. The three major substrate solutions being used for this experiment are glucose‚ maltose‚ and alanine. The issues this experiment addresses are cellular respiration occur in different stages which are glycolysis‚ citric acid cycle‚ and fermentation. In this lab the experiment determines the effect of different substrates on

type of respiration in animals. All plants and animals do cellular respiration. Respiration is the release of energy‚ which occurs in the living things’ cells. Cellular respiration is the use of glucose and oxygen to yield ATP which is usable energy. Glucose is broken down into glycolysis‚ which is then used to make ATP. ATP is the usable form of energy which allows organism to function. Almost all organisms do cellular respiration‚ others do anaerobic respiration. Cellular respiration is a part

Understanding the function of cellular respiration and fermentation is easy to learn. However it is more difficult to learn the process of glucose being converted into energy. Cellular respiration has four stages‚ of which a phase can consist of eight or ten steps. In the Krebs Cycle alone‚ there are ten steps‚ where the input of Acetyl CoA is eventually reconverted back into oxaloacetate. Fermentation is also no different. It can be difficult for students to understand what the role of NADH

1 Two critical ingredients required for cellular respiration are glucose and oxygen. Cellular Respiration‚ process in which cells produce the energy they need to survive. In cellular respiration‚ cells use oxygen to break down the sugar glucose and store its energy in molecules of adenosine triphosphate (ATP). Cellular respiration is critical for the survival of most organisms because the energy in glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of

plant. Plants and trees cover about thirty percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves to make sugar from carbon dioxide‚ or CO2‚ which is in the

inorganic cofactor such as Magnesium to the rate of respiration of yeast was determined using Durham tube assembly with the substrate glucose. After thirty minutes‚ the test tube with the cofactor in the form of Magnesium sulphate MgSO4 showed the higher amount of carbon dioxide evolved which was measurable through volume and was one of the by- products of cellular respiration. This stated that the higher amount of CO2 evolved‚ the higher the rate of respiration. Thus‚ the hypothesis “If enzymes need cofactors

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.
