    Title: Amount of Oxygen‚ Mung Beans (Vigna Radiata) Consume during Cellular Respiration Introduction: Cellular respiration is a catabolic reaction that refers to the process of converting chemical energy of organic molecules into a simplify form so it can be used immediately by organism. Glucose may be oxidized completely if sufficient oxygen is available‚ by the following equation: C6H12O6 + 36 ADP + 36Pi + 6O2(g) 6 H2O + 6 CO2(g) + 38 ATP + heat All organisms‚ including plants and animals

    ‘Respiratory regulation’ refers to changes in pH due to pCO2 changes from alterations in respiration. This change in can occur rapidly with significant effects on pH. Carbon dioxide is lipid soluble and crosses cell membranes quickly‚ so changes in pCO2 result in rapid changes in [H+] in all body fluid compartments. Respiratory regulation requires a connection between alveolar respiration and pH via pCO2. The control system for respiratory regulation of acid-base balance can be considered using

    M1- Discuss the role of energy in the body‚ describe the process of cell respiration and give three examples of how energy is used in the human body Every living cell needs energy. The form of energy that we use is chemical energy in the form of glucose that we get in our food‚ mainly from carbohydrates such as bread‚ pasta and potatoes. Living cells cannot function without energy‚ which can then lead to death. To release the energy from glucose‚ oxygen is added (oxidise glucose) by breathing continuously

    Respiration is a process which releases energy from energy-rich molecules such as glucose. The glucose is converted into energy which is usable for life processes. Burning‚ or combustion‚ is a reaction between a substance and a gas to release energy. These two reactions have many similarities but are not the same. This essay will identify some of similarities and differences between the two processes. The first similarity is that both respiration and burning use oxidation to release energy. In respiration

    parts. THE DIGESTIVE SYSTEM Digestion is a process of breaking down large complex food substances into simple molecules that can be used by each cell. Most of the foods of organisms consist of carbohydrates‚ fats‚ and proteins. Each of these large molecules acted upon by special kinds of digestive systems that speed up digestion by hydrolysis or splitting of molecules. Food also includes smaller molecules such as water‚ minerals and vitamins. DIGESTION IN PLANTS Plants do not have

    in the body. The chemical equation for cellular respiration is: C6H12O6 + O2 = E + CO2 + H2O OR Glucose + Oxygen = Energy + Carbon Dioxide + Water In order to release energy we need glucose which is a simple carbohydrate that is produced after digestion of food and we also need oxygen. Once the food has been broken down it then needs to be transported throughout the body. For this reason‚ there are three systems involved in cellular respiration. These three systems are known to be the digestive

    and blood circulation. (Wright‚ 2007) We get energy from the foods that we eat. Metabolism is a chemical activity which uses cellular respiration. (Wright‚ 2007) Aerobic respiration is respiration with oxygen present. (Wright‚ 2007) The formula for cellular respiration is below: Glucose +oxygen = Energy‚ carbon dioxide and water. Carbon dioxide and water are the waste products from creating energy. Respiration can happen without oxygen. This process is called anaerobic respiration. The equation

    qualities. The E stands for European which means it is approved by Europe. Digestion and Absorption: - Digestion is the breakdown of food into smaller particles or individual nutrients. It is accomplished through six basic processes‚ with the help of several body fluids—particularly digestive juices that are made up of compounds such as saliva‚ mucus‚ enzymes ‚ hydrochloric acid‚ bicarbonate‚ and bile . The six processes of digestion involve: (1) the movement of food and liquids; (2) the lubrication of
