The topic I have chosen to look at in this essay is to "discuss the principal ways in which heat is gained by and lost from the body‚ and explain the various mechanisms involved in regulation of body temperature. Briefly indicate how excessive cold and heat affect the body". The body gains and loses heat through the external environment by radiation‚ conduction‚ convection and evaporation of water. These are all physical mechanisms known to the human body. (Vander‚ Sherman & Luciano 1998). Radiation

Physiology‚ Berry HOMEOSTASIS LAB ACTIVITY Introduction: Homeostasis means maintaining a relatively constant state of the body’s internal environment. The term used to describe a pattern of response to restore the body to normal stable level is termed negative feedback. When a stimulus (environment change) is met by a response that reverses (negates) the trend of the stimulus‚ it is negative feedback. As a result the internal environment is returned to normal. Pulse rate is constantly checked

March 6‚ 2013 Abstract Enzymes are very specific protein because they contain one active site on their surface that enable the substrate to bind to the enzyme and form the enzyme substrate complex and then release the products. The principal function of enzymes is to increase the rate of the chemical reactions. Enzymes have a set of conditions at which they work perfectly; this is known as optimal condition. Fungal and bacterial amylase are the enzymes that we going to study for their

Acetylcholinesterase and Butyrylcholinesterase substrate selectivity and various acting cholinesterase inhibitors Introduction Cholinesterases are a group of enzymes present in mammals which breakdown certain neurotransmitters by hydrolyzing the ester bonds within a molecule (Rang & Dale‚ 2007). There are two major types of enzymes‚ acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Though similar in structure‚ they differ in distribution‚ function and substrate specificity. AChE is

Cassie Ho Period 1 Physiology September 16th 2014 Lab 1: Homeostasis Background Information The conditions in our bodies do not really change at all. Our body temperature has to stay within a certain range in order to function. We maintain these function through a process which is called homeostasis. Homeostasis is the process of maintaining a constant internal environment such as body temperature‚ blood pressure‚ and heart rate. An analogy to help explain homeostasis is a student walking up the

By: Jeffrey Palumbo 20523300 For BIOL 130 Tutorial Section 116 Shirley Chan The Importance of Peroxisomal Proteins in the Human Body Peroxisomes are small organelles found in almost all eukaryotic cells that contain a variety of enzymes and are responsible for an assortment of essential metabolic processes (Wanders‚ 2013). Generally‚ these processes include the β-oxidation of fatty acids and the detoxification of reactive oxygen and nitrogen species. In order for these reactions
