Unit 5: Anatomy and Physiology (P4) Explain the physiology of two named body systems in relation to energy metabolism in the body In this task I am going to discuss the three systems involved in energy metabolism 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

note chances if any. Ethanol emulsion test The ethanol emulsion test is a test for lipids. Lipids is not soluble in water therefore ethanol is used to dissolve it. The lipids dissolved in ethanol is to be then decanted in water. This results in the suspension of small globules of lipids dissolved in ethanol in water such that they both will not mix. Cloudy white emulsion will indicate the presence of lipids. Adding water to the solution results in emulsion of tiny droplets in the water. These

In this lab‚ homeostasis will be studied upon the two eggs in corn syrup and distilled water‚ and in each sucrose solution with different amounts of molarity. Homeostasis is the maintenance of balance between an organism or cell and its environment. Without homeostasis‚ many important aspects of the body such as body temperature‚ blood sugar‚ heart rate‚ blood rate‚ and pH of blood would not be kept at the proper balance. This could eventually result in death due to improper amounts of certain substances

Two processes allow organisms to gain heat: metabolism of food and absorption of solar energy. In a previous experiment‚ food was heated up to experimental temperature and fed to lizards. The lizards were then placed in a metabolic chamber‚ and measurements were taken for elevated metabolism at 35 degrees Celsius. An hour later‚ measurements were taken again at 24-26 degrees Celsius. Minimal endothermy was determined

measures taken from calorimetry. Studies also showed that by eliminating the sex differences that occur with the accumulation of adipose tissue by expressing metabolic rate per unit of "fat-free" or lean body weight‚ the values between sexes for basal metabolism are essentially the same. Exercise physiology textbooks have tables to show the conversion of height and body surface area as they relate to weight and basal metabolic

Biodegradation OF Xenobiotics . OVERVIEW Microorganisms play an important role in the removal of synthetic organic compounds from the environment. This chapter gives an overview of the evolution of biodegradation pathways and describes the strategies that microorganisms have evolved to transform important molecular structures. The actual effectiveness of biodegradation in the environment is determined by the bioavailability of the
