Concentration on the Rate of Enzyme Catalysed Reaction To investigate the effect of concentration on the rate of enzyme catalysed reaction I must know all the factors that affect it in order to investigate in this. Here are all the factors: Temperature- Enzyme like it warm but not too hot. Enzymes are biological catalysts‚ which speed up chemical reactions. They work most efficiently at the optimum point (37°C). If they are below 37°C they will work slower. If the temperature goes over

- 2 Marbles of different mass‚ one steel and one nylon - Dropping Mechanism with a lever to hold the marble and pull for drop - Bee Spi (measures velocity in kilometers per hour.) - Box to catch the marble on the way down Procedure The dropping mechanism was set up‚ with the BeeSpi attached to it at 26.5” from the lever that drops it so that the marble would fall through it‚ therefore recording the velocity in km/h. There was also a box at the bottom of the mechanism to catch the marble every

Caffeine...Does it truly affect the body? Everyday millions of Americans go through cups of coffee a day and most people don’t even know how it affects your body. I am one of those people and I have always wondered what caffeine does to my body. This topic interest me a lot because I drink coffee on a daily about 2 times a day and I want to know if there are any short term effects and long term effects and if I should be worried about drinking too many drinks with caffeine in them. I want to find

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

EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

fixed exchange rate system that fixes the exchange rate of Hong Kong Dollar and United State Dollar to a ratio of 7.8: 1 Hong Kong Monetary Authority does not need to stable exchange market by controlling the supply and demand of HKD. It can be stabilized by Fixed-linkage System. In the past 15 years‚ Hong Kong interest rates and exchange rates fluctuated in the same trend of the US interest rate and exchange rate. The graphs below show an example of interest rate and exchange rate respectively:

Variable was the heat lamp‚ and the dependent variable was the temperature of the soil‚ because the temperature varied based on whether the heat lamp was turned off or on‚ and whether there was extra water added or not. Our hypothesis was proven correct‚ because the dry soil’s temperature was hotter than the damp soil’s temperature when the heat lamp was on‚ but then it decreased when it turned off‚ while the damp soil’s temperature remained the same. This is because dry soil contains little moisture
