P5. Homeostasis is the process by which a constant internal environment is maintained by our body. For instance‚ this means that in our body‚ temperature‚ blood sugar levels‚ etc must be kept within a narrow range even when we are in a freezing climate‚ or while doing vigorous exercise etc. All homeostatic control mechanisms have at least three interdependent components which are: The receptor responds to changes in the environment‚ for example‚ detects temperature change. Then‚ after the receptor

level. Our normal level of blood glucose is approximately 90 mg per 100cm3‚ and must be kept this way via the liver. The liver withdraws excess glucose from the plasma solution and either uses it for muscle respiration during exercise or stores it as glycogen in the hepatocytes. When the level of blood glucose decreases‚ it is

Anabolism and Catabolism Anabolism and catabolism are two phases of the human body’s metabolic process. Metabolism is a process that is essential for humans to live a healthy and productive life. The anabolism phase is the process where the body builds up the needed molecules. This phase requires energy in order to complete the process. Catabolism releases energy that can be used by the organism. This phase is the process of breaking down the complex molecules into smaller portions. These two

The Physiology of Fitness Assignment 1 Helpsheet Step 1 You need to introduce your assignment‚ here I would define two key terms for the entire of this assignment these are chronic and acute. Example Answer There are many changes to the body during exercise; these can be classified as acute and chronic. Acute meaning they are short term and happen almost instantly with the onset of exercise. The other chronic is long term and allows the body to adapt its capabilities so therefore it

Licheniformis and the fungus; Aspergillus Oryzae was used to examine how changes in temperature of the enzymes affects the rate of the reaction with starch. Amylase is an enzyme‚ found chiefly in saliva and pancreatic fluid‚ that converts starch and glycogen into simple sugars. This enzymatic reaction therefore needs the utilization of water molecules. This is why the reaction is called a hydrolytic reaction and therefore‚ undergoes a procedure referred to as hydrolysis.

Intensive Care Nursery House Staff Manual Inborn Errors of Metabolism INTRODUCTION and PATHOPHYSIOLOGY: Inborn Errors of Metabolism (IEM) comprise a group of disorders in which a single gene defect causes a clinically significant block in a metabolic pathway resulting either in accumulation of substrate behind the block or deficiency of the product. All IEMs are all genetically transmitted typically in an autosomal recessive or X-linked recessive fashion. The major categories are: Organic

The liver is the largest organ in the entire‚ normal human body. It weighs anywhere from 2.5 to 3.3 pounds. With its large size it is also a very resilient organ. Up to 3/4 of its cells can be removed before is ceases to function. It is red-brown organ roughly shaped like a cone. The liver is located in the upper right abdominal cavity immediately beneath the diaphragm. Without the liver‚ we could not survive. It serves as the body’s chemical factory and it regulates the levels of most of the main
