Exam: 46.4‚45‚47‚48 Lecture outline for the zoology unit revised 2010 Introduction to animal form & function and regulation of TB (ch. 40 & Concept 42.4) This first reading assignment reviews 5 major principles re living organisms: 1. Physical laws & the environment constrain the size & shape of organisms. 2. Form & function are correlated at all levels of organization. 3. Chemical energy in food is used to sustain form & function. 4. Many animals (& other organisms) regulate

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

ferment or pickle not only is it changing the color‚ the flavor and the texture fermenting can have healthy benefits as well‚ when something becomes fermented and begins going through the transformative change what is happening is that starches (amylase)‚ proteins (protease) and fats or lipids in lipase take these complex molecules and turn them into simple easily digestible compounds where vitamins are synthesized increasing the levels of the vitamins B-12 which can be harder to find in a regular

Enzyme Kinetics Marcos‚ Nelissa S. Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established

stomach lining and producing stomach ulcers. Water is also needed to lubricate the intestines to facilitate the passing of waste through the intestines into the colon. It is the prime component of saliva which moistens the mouth and contains the enzyme amylases which allows the breakdown of food to occur. Membrane layers also contain water which allows organs to move slightly with body movement without being damaged. Lubricant is also found between joints so that the cartilage is able to provide a smooth

The small intestine (or small bowel) is the part of the gastrointestinal tract following the stomach and followed by the large intestine‚ and is where much of the digestion and absorption of food takes place. It receives bile juice and pancreatic juice through heptopancreatic duct‚ controlled by Spincter of oddi. Ininvertebrates such as worms‚ the terms "gastrointestinal tract" and "large intestine" are often used to describe the entire intestine. This article is primarily about the human gut‚ though

Problem Set 1 1. Explain lipoprotein physiology and metabolism (Chapter 15). - Lipoproteins are a biochemical formation that aid with the transporting of lipids. The four major pathways include Lipid absorption pathway‚ exogenous pathway‚ endogenous pathway and reverse cholesterol transport pathway. All of these pathways are dependent on a particular particle know as apo-B that contains lipoproteins which‚ functions as a transport for dietary and Hepatic lipids to the outer layers of the cells

People run differently in bare feet‚ some are more likely to land on their forefoot or midfoot compared with people running with shoes on‚ who tend to land on their rear-feet. Some reports say that barefoot running leads to reduced injury rates. When children are wearing shoes‚ they take longer steps than when they are barefoot. The Tarahumara participate in ultra-long distances across canyons while barefoot or wearing minimal sandals. Over the decades‚ there have been many reports of superhuman
