ANAEROBIC AND AEROBIC METABOLISM Lab 5 BCEM 341 – Winter 2014 Nebojsa Kuljic 10066717 Partner: Kendra Skalyn B02 Introduction Cells of all organisms can obtain energy through the combustion of sugars‚ either in the presence of oxygen (Aerobically) or without oxygen (Anaerobically). The purpose of this experiment was to perform a quantitative investigation of the differences between Anaerobic and Aerobic metabolism using pea seedlings and yeast organisms [1].

HW Review for Photosynthesis exam: Due Monday March 28 Reminder your lab write up will be a next week. If your lab is this Friday you also will get a week to complete your full lab write-up. Sample questions: 1. twenty-five plants were placed in each of four closed containers and then exposed to light conditions shown in the data table below. All other environmental conditions were held constant for a period of 2 days. At the beginning of the investigation‚ the quantity of CO2 present in each closed

Lab 8 Cellular Respiration and Fermentation Objectives: 1. Observe the effects of cellular respiration on temperature in a closed system. 2. Investigate carbon dioxide production in both germinating pea seeds and crickets. 3. Perform an investigative study of the rate of cellular respiration in both pea seeds and crickets at various temperatures. 4. Compare the alcoholic fermentation of glucose‚ sucrose‚ and starch by yeast. Introduction All organisms must have a continual

Gas exchange in animals External respiration: not to be confused with cellular respiration‚ although purpose is to provide oxygen and eliminate carbon dioxide Single-celled organisms achieve this by simple diffusion Larger organisms need specialized breathing organs Getting the air into the body is one challenge Circulatory system needed to distribute oxygen to the tissues Specialized blood cells can transport oxygen (solubility in plasma is very low) The process of breathing Air has much

Aerobic vs Anaerobic Cardiovascular vs Resistance Training I’ve heard the terms aerobic and anaerobic a lot. What do these terms actually mean and are they important for my exercise program? ANSWER: Strictly speaking‚ the terms "aerobic" and "anaerobic" refer to the presence and absence of oxygen‚ respectively. Most of our cells prefer to get their energy by using oxygen to fuel metabolism. During exercise with adequate fuel and oxygen (i.e.‚ aerobic)‚ muscle cells can contract repeatedly

Photosynthesis Abstract: An experiment was carried out to determine how certain factors such as light intensity and availability of carbon dioxide‚ affected the rate of photosynthesis. The rate of photosynthesis was measure by the amount of oxygen produce (cm3/min). A valid conclusion was made and most of the results were in accordance with the prediction‚ although there were some anomalies present. The errors and limitations were evaluated and some improvements were suggested. Introduction: Photosynthesis

you know the difference between aerobic and anaerobic exercises? What about the benefits they both give and which one benefits you most? Aerobic exercises also called cardiovascular exercises are any sustained‚ rhythmic activity that affects the large muscle groups and makes the lungs work harder as the body’s need for oxygen increases. Many benefits come with doing aerobic exercises. According tohttp://www.newellness.com/physfitn/benaero.htm‚ “Aerobic exercise improves the strength of

Sarwal AP Lab 4 Determining the rate of Cellular Respiration Using Germinating and Dry Peas Purpose: To determine the rate of cellular respiration using dry and germinating peas. Introduction: In this lab‚ we are investing cellular respiration‚ specifically aerobic cellular respiration. Aerobic cellular respiration is the process by which cells consume oxygen during the oxidation of glucose and produce CO2 as a byproduct. During cellular respiration‚ glucose is split into a 6 carbon sugar‚ G3P through
