cannot be used as directly by cell as a source of energy so cells use ATP as their immediate source of energy. * This conversion of glucose into ATP takes place during cellular respiration and there are 2 different forms of cellular respiration depending upon whether oxygen is available or not * Aerobic respiration requires oxygen and produces CO2‚ water and lots of ATP. * Aerobic has 4 stages: 1) Glycolysis – the splitting of the 6-carbon glucose molecule into 2 3-carbon molecule

Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air‚ but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Here is a molecular model of a glucose molecule. You do not need to memorise the diagram for you GCSE exam‚ but it should help you to understand that a molecule of glucose contains six atoms of Carbon (shown in blue)‚ twelve

Lab 04: Sugar Respiration in Yeast Sugars are vital to all living organisms. The eukaryotic fungi‚ yeast‚ have the ability to use some‚ but not all sugars as a food source by metabolizing sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. The decomposition reaction that takes place when yeast breaks down the hydrocarbon molecules is called cell respiration. As the aerobic respiration breaks down glucose to form viable ATP‚ oxygen gas is consumed and carbon

Microorganisms Anaerobic respiration takes place in yeast and some bacteria‚ producing ethanol and carbon dioxide. They have been used in the making of many foods such as bread‚ yoghurt and vinegar‚ Lactic acid bacteria are the key ingredient in yogurt production as they they initiate the fermentation process. Many of the species used in yogurt provide added health benefit to those who eat them regularly and are often referred to as probiotics. Probiotics are believed to strengthen your immune

of them require it. Organic carbon molecules are the energy source‚ and for waste is carbon dioxide (CO2) and water (H2O). CO2 can combine with water to form carbonic acid during cellular respiration. Phenolphthalein can be used to help detect any changes in pH because of production of CO2 during cellular respiration. Phenolphthalein usually appears clear or colorless in acidic solutions‚ and red in basic solutions. Procedures: In the first lab‚ seven test tubes were attained and six of

Cellular Respiration  Cellular respiration is the process of oxidizing food molecules‚ like glucose‚ to carbon dioxide and water. C6H12O6 + 6O2 + 6H2O → 12H2O + 6 CO2 The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis‚ the breakdown of glucose to pyruvic acid the complete oxidation of pyruvic acid to carbon dioxide and water In eukaryotes‚ glycolysis occurs in the cytosol.
