Substrate concentration and yeast catalase Aim: To see how the substrate concentration in hydrogen peroxide affects the rate of an enzyme controlled reaction using yeast catalase. Introduction: An enzyme is a biological catalyst made of protein. Enzymes are protein molecules found in living organisms and in this case I will use a yeast catalase. Catalase is an enzyme that catalyzes the reduction of hydrogen peroxide. Hydrogen peroxide is a poisonous by-product of metabolism‚ so it is very

CH 202 Breakdown UV/Vis: Molecules containing π-electrons or non-bonding electrons (n-electrons) can absorb the energy in the form of ultraviolet or visible light to excite these electrons to higher anti-bonding molecular orbitals. The more easily excited the electrons (i.e. lower energy gap between the HOMO and the LUMO)‚ the longer the wavelength of light it can absorb. Conjugation raises the energy of the bonding orbitals and lowers the energy of the antibonding molecular orbital. This

High-fructose corn syrup (HFCS) is a fructose-glucose liquid sweetener alternative to sucrose (common table sugar) first introduced to the food and beverage industry in the 1970s. It is not meaningfully different in composition or metabolism from other fructose-glucose sweeteners like sucrose‚ honey‚ and fruit juice concentrates. HFCS was widely embraced by food formulators‚ and its use grew between the mid-1970s and mid-1990s‚ principally as a replacement for sucrose. This was primarily because

Communication Breakdown Deborah Tannen in her essay “Sex Lies and Conversation” points out the problems in communication between genders. She focuses on conversational styles and on how a person’s expectations of one’s reaction may cause misunderstanding. She emphasizes the importance of something she calls cross cultural communication. Tannen believes that in order to communicate properly with the opposite sex we must learn their culture and adapt to conversation with them. First‚ Tannen describes

The thresholds over these stages range from‚ ‘I can’t stand this anymore‚’ (intrapsychic) to ‘It’s not inevitable‚’ (grave-dressing.) Lee’s model of relationship breakdown is similar to Duck’s yet it sees breakups as happening over a period of time rather than a single event‚ he split it up into five stages. >Dissatisfaction‚ one or both partners realise there are problems in the relationship >Exposure‚ the problems

Product Breakdown Structure Toolkit 1. Overview If your are familiar with PRINCE2 pre-20091‚ you’ll know that it recommended the use of a number of techniques‚ one of which is Product Based Planning. A Product Breakdown Structure (PBS) is an essential part of this‚ its purpose being to define the products (deliverables) of a project and how they relate to each other. Product Based Planning has four components: • Product Description: a description of the overall project deliverables. In

A work breakdown structure is a deliverable-oriented grouping of the work involved in a project that defines the total scope of the project. Since many projects involve many people and many different deliverables‚ it is important to organize and divide the work into logical sections based on how the work will be performed. The work breakdown structure is a foundation document in software project development management because it provides the basis for planning and managing project schedules‚ costs

Blanche’s lifelong habit of avoiding unpleasant realities leads to her breakdown as seen in her irrational response to death‚ her dependency‚ and her inability to defend herself from Stanley’s attacks.

bottled foods and drinks we buy in the store‚ you find that 99% of them contain “high fructose corn syrup”‚ which is basically pure sugar. This means that the food industry is feeding a nationwide sugar addiction that is leading to a huge diabetes epidemic. It’s also interesting that the US government gives multibillion-dollar subsidies to the agribusiness corporations that grow and sell corn that ends up as high fructose corn syrup. Don’t you think our government should be working to protect our health
