Temperature Affecting Enzyme Activity Introduction The basic properties of life revolve around chemical reactions. Without the presence of enzymes some of life’s processes would not come so easily. Enzymes are basically proteins‚ which have specific shapes for different substrates. Enzymes change the rate in chemical reactions. It does this without having to change its own shape‚ which makes enzymes different from other proteins. A common enzyme that we have is catalase‚ which breaks down

project is to demonstrate how water temperature affects the dissolving of sugar in liquid. Everything in our universe is made up of particles which are in constant motion. In a solid state particles move the slowest while in a liquid state particles move the fastest. Under the right conditions‚ solid particles (the solute) when mixed in liquid (the solvent) can form a solution. This occurrence is called dissolving. I wanted to answer the question; does the temperature of water affect the speed at which

The effect of temperature on a reaction rate In this experiment I shall be investigating how temperature affects the rate of reaction Rates of reaction The Factors that affect the rate of reaction are temperature‚ surface area‚ concentration‚ catalysts‚ light and pressure Surface area – Surface area is the amount of solid surface that is available for reaction - Only affects solids so this will not affect our

is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water is 0° C or 32° F. The temperature may be lower

The relationship between shape and diffusion rate Aim- To investigate the relationship between the shape of an object and the time taken for a substance to diffuse to its centre. Hypotheses- Part A) The 5x5x2.5mm block will turn clear first as the Surface area to volume ratio is high and the 10x10x10mm block will take the longest to completely diffuse the Acid to its centre. Part B) The flat‚ rectangular block will be the first to completely turn clear due to its high Surface Area/Volume Ratio

substances catch fire at a different temperature. The lowest temperature at which a substance catch fire is called its ignition temperature. Combustible substances do not catch fire or burn as long as its temperature is lower than its ignition temperature. Now let me do an activity which tells you why reaching ignition temperature is necessary to burn an object. You know that paper catch fire with a flame. Let me

Darren Sasko 9/22/14 What are the various factors that shape identity? Identity is something we all acquire over our lifetimes. There are many factors that come in to play when developing your personal identity. Every-day things and interactions between inanimate objects and people we come in contact with are all factors in how are identity is shaped. There are many theories as to what is most important in forming our identities. Society has a major impact on who we become. When we form relationships
