Maintaining a Balance1. Most organisms are active in a limited temperature range1.1. identify the role of enzymes in metabolism, describe their chemical compositions and use a simple model to describe their specificity on substratesRole of Enzymes: enzymes are organic catalysts which cause chemical reactions to proceed which could not normally occur under normal conditions found in cells. For example:Sucrosesucrase glucose + fructose(substrate) (enzyme)The enzyme sucrase is very specific and will break down only sucrose molecules.Maltose maltaseglucose + glucose(substrate)(enzyme)Cattle, kangaroos, sheep, etc., consume lots of cellulose.cellulosecellulose glucosefats (lipids) lipase fatty acids + glycerolprotein protease amino acidsTheir role in metabolism: metabolism is the sum of all reactions taking place inside a cell. Enzymes role in metabolism is to maintain the rate of chemical activity. The catalyst can be reused many times.The chemical composition: Enzymes are proteins. There are 20 different types of amino acids. The type of amino acid, the number and the arrangement of these amino acids in a 3-D shape structure gives the protein a particular shape which makes it specific to only one type of reaction.Lock and key method: The active site of the enzymes is shaped in such a way that the substrate molecules can be bound together causing a reaction to occur. The substrate is the key and the active site of the enzyme is referred to as the lock.Induced fit model: In this model, if the substrate molecules do not fit into the active site, then the enzymes can slightly modify its active site to allow the substrate to fit into it. Once the molecules are joined together, the enzyme will return to its original shape.1.2. identify the pH as a way of describing the acidity of a substanceIf you are given the pH of a substance, this indicates whether it is acidic, basic or neutral. It has a numerical scale of 1-14. 1 is most acidic, 7 is neutral, and 14 is most basic.1.3. explain why the maintenance of a constant internal environment is important for optimal metabolic efficiencyThere are certain optimum conditions for enzymes to function best. If these conditions are not maintained, then the enzymes role in metabolism may be affected.Conditions that need to be maintained for metabolic efficiency:1.temperature - in mammals, the best temperature is around 37°C. At temperatures above the rate at which enzymes catalyse, the metabolic reactions described are affected (at high temperature, there may be structural denaturing).2.pH - enzymes work best at a particular pH. Any variation in pH (either increase or decrease) affects the rate of metabolic reaction.3.co-enzymes (which contain chemicals - mineral ions/vitamins) help in the functioning of enzymes. The internal environment has to be maintained to a specific level for enzymes to work at its maximum rate.1.4. describe homeostasis as the process by which organisms maintain a relatively stable internal...

How Support from Employers on Work- Life Balance Affects Employee Performance

2319 words - 10 pages . Carney, and Morgan Wilkinson (2012), the authors propose that the process of work life balance is either situational or absolute. The absolutist perspective consists of achieving time balance, involvement balance, and satisfaction balance. Thus, the individual is successful with maintaining work life balance when they are equally content and happy across all domains. The situational model emphasizes more in the area of a person’s own values and
