10.19.2011 TITLE: The Importance of Oxygen for Life PURPOSE: To determine whether test tubes filled with bacteria‚ a few salts‚ distilled water‚ and glucose would grow in the presence or absence of oxygen. By adding oxygen to certain tubes and withholding it from other tubes‚ one can determine which bacteria grow the most efficiently. HYPOTHESIS: The test tubes of bacteria with oxygen will grow and thrive over the test tubes without oxygen. METHODS: Using the data shown in Table 7-A-1

Unit 2 Assignment Critical Thinking 1. Explain why‚ even under ideal conditions‚ Streptococcus grows slowly. Cellular respiration is a process in which glucose is broken down to form an energy that can be used by the cell. There is aerobic respiration and there is anaerobic respiration. Aerobic respiration involves a series of chemical reactions in which oxygen is used to transform into carbon dioxide and H2O. This process generates energy carrying molecules called ATP. Anaerobic respiration

The Effect of Microwave Radiation on the Respiration Rate of Phaseolus vulgaris Aerobic Celluar Respiration is a process that is carried out by most living organisms. The process is a series of chemical reactions that occur within the mitochondrial matrix and cristae of eukaryotic cells. Following the anaerobic process of glycolysis‚ partially broken down sugar molecules enter the matrix of the mitochondria where they are further reduced by oxygen. In the process‚ a small amount of ATP is created

Electron Transport Chain The first step in the electron transport chain process is for the NADH2 produced during glycolysis‚ the intermediate step‚ and the citric acid cycle to be attracted to Complex I (FMN ·FeS)due to its high affinity for NADH2. This attraction pulls NADH2 to Complex I (NAD dehydrogenase) and the two electrons from H2 are pulled off by the FeS (ferrous sulfate) leaving two H+ ions and NAD+. These molecules repel each other and this results in the NAD+ being recycled

Protocol for Lab 5 – Aerobic Respiration Part 1 Isolation of Mitochondria from Cauliflower - Weigh 50g of rosettes cut from fresh cauliflower head. - Cut rosettes and place it on ice - Prepare juice extractor by placing ice and an empty 150 ml beaker into the right compartment. - Collect pulp from left compartment and record total volume of the extract. Approx. 20ml - Filter the pulp using six layered cheese cloth and collect it in a beaker sitting on ice. - Place two 50 ml test tubes

Cellular Respiration Study Guide 1. What is cellular respiration? Cellular respiration is the process by which cells get their energy from food. It is a pathway where ATP is produced from the working cells. 2. What are the raw materials for cellular respiration? The raw materials are glucose and oxygen. 3. What is the simple reaction for cellular respiration? C6H12O6+6O2=6CO2+6H2O+Energy 4. Why is it not practical for an organism to release all

March 5‚ 2013 Biology 1111 Term Paper Glycolysis and the Citric Acid Cycle Glycolysis occurs in the cytoplasm outside the mitochondria‚ it is a metabolic pathway that is the breakdown of glucose (C6) and ends with 2 pyruvate (C3) molecules. Energy is invested to activate the glucose‚ 2 ATP are gained‚ and oxidation results in NADH‚ which will be used later for additional ATP production. Glycolysis is divided into (1) the energy-investment step‚ when ATP is used; and (2) the energy-harvesting

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric
