Located in the cytoplasm‚ they are the sites of cellular respiration which ultimately generates fuel for the cell’s activities. Mitochondria are also involved in other cell processes such as cell division and growth‚ as well as cell death. They convert oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell’s metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Mitochondria

through cellular respiration (The process in which a cell breaks down sugar or other organic compounds to release energy used for cellular work). This process includes glycolysis‚ pyruvate oxidation‚ the kreb cycle‚ and the electron transport chain. The theoretical ATP output by this process is 36 ATP per glucose (C6H1206). Lipids are broken down to fatty acid chains and through a process called beta oxidation; the fatty acid chain is broken down to many acetyl-Co A‚ which then enters cellular respiration

about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration‚ the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration‚ the production of lactate during which the muscles have a limited supply of oxygen‚ and however keep working despite this. Aerobic respiration requires oxygen

Burning peanuts to simulate cellular respiration This lab will be assessed on Conclusion & Evaluation. Aim To determine the average energy content of 1g of peanut. Method 1. Set up a clamp stand so that it is holding a 100cm3 beaker. 2. Using a measuring cylinder‚ pour 50cm3 of water into the beaker. 3. Use a thermometer to record the temperature of the water. 4. Place some aluminium foil over the beaker to prevent heat loss. 5. Record the mass of a peanut using an electronic balance

Gazdik Biology Department Ferrum College‚ Ferrum VA Part I – The Symptoms Imagine that you work at the medical examiner’s office for a major metropolitan city. As Chief Medical Officer‚ you investigate suspicious deaths and provide toxicology services for the county. Unfortunately‚ it’s been a busy week. In the past five days‚ seven people have died‚ all with similar

Adenosine Triphosphate Adenosine triphosphate (ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell‚ and essentially all the physiological mechanisms that require energy for operation obtain it directly from the stored ATP. (Guyton) As food in the cells is gradually oxidized‚ the released energy is used to re-form the ATP so

The energy released when a molecule of ATP is hydrolyzed (ATP ADP + PO4) is used to drive cellular reactions. To stay alive‚ a cell must continually regenerate its supply of ATP (from ADP

Experiment on Cellular respiration of Mung Beans Seeds with the Effects of Temperature Introduction: ATP is generated from aerobic respiration from the use of biosynthetic pathways. Glycolysis is where respiration starts in the cells and produces ATP‚ NADH‚ and 2 pyruvate molecules from the oxidation of six carbon carbohydrate and glucose. Even if oxygen is there or not‚ enzymes are mediated in the cytoplasm. The electron transport chain‚ chemiosmosis‚ and aerobic respiration use NADH molecule

ATP and its Role in Living Organisms An exemplary biology essay ATP (adenosine triphosphate) is vital to living organisms. It acts as a short-term store of energy in a cell‚ carrying it from where it is synthesised (e.g. the mitochondria) to where it is needed for biological processes. It is well suited to this job for the following reasons: it is small and soluble (and so can be easily transported around a cell); it is easily broken down to release energy; it can transfer energy to other molecules;
