investigate the effect of substrate concentration Hydrogen Peroxide H O (in %) on the rate of reaction of the enzyme catalase (in 1/mean time). Prediction: As the substrate concentration (hydrogen peroxide) in % increases the rate of reaction in 1/mean rate increases until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The rate steadily increases when more substrate is added because

could see the reaction on them and study the cause and effect of each one. Literature Search A mealworm at that stage can be around 35mm. long. A mealworm is nocturnal. They eat dry leaves‚ grass‚ dead insects and other animals. They will not eat sound wood. They carry a disease called gastrointestinal infestations‚ which is highly dangerous when consumed by humans. They are yellow mealworm for only a short 6 to 18 days. Mealworms are more likely to be in the northern cooler states.

Date: 14th-15th October Title: The effect of the concentration of hydrogen peroxide on catalase Aim: to examine how the concentration of the hydrogen peroxide affects the rate of reaction Hypothesis: The substrate concentration will determine the rate of reaction. The reaction will increase as the concentration increases‚ but from a certain concentration‚ the rate will maintain the same rate Materials: 3% hydrogen peroxide 6% hydrogen peroxide catalase round metal basin measuring cylinder

Practical Assessment 2 – The effect of substrate concentration on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and

ID:0720052 Effect of an Increasing Substrate Concentration on Enzyme Activity Rate Abstract The reaction rate of an enzyme can be affected by many factors‚ and the purpose of this experiment was to find out how an increasing substrate concentration influences the rate of an enzyme activity; we obtained data from recording the absorbance of the samples which contain the same amount of potato juice (enzyme oxidase) and different amount of catechol (substrate) while holding pH and temperature
Premium Enzyme Catalysis
The effect of increasing substrate concentration on rate of an enzyme reaction. Enzymes are biological catalysts that lower a reactions activation energy making possible many of the reactions needed for life to exist. Enzymes have a high specificity which have been explained by many theories such as Fischer’s lock and key. Currently the most widely accepted theory is the induced fit hypothesis proposed by Koshland in 1958. This hypothesis solves some of the problems with the Lock and key theory

The mealworm goes through complete metamorphosis to become a beetle‚ so its starts out as an egg. The eggs are white and tiny: only about two mm long and about 0.9 mm wide. They remain an egg for four to nineteen days before hatching. After hatching‚ they enter the larvae stage. During this stage‚ the mealworms spend all their time eating and growing/shedding their exoskeletons. They can shed their exoskeletons anywhere between nine and twenty times. They do this because their old skin becomes too

The Effect of Education on Economic Growth Abstract Education is one of the primary factors of development. Countries can’t achieve economic development without investment in human capital. Vocational training and higher education equip a worker to perform certain jobs or functions .It improves the quality of their lives and leads to social benefits to individuals and society like improving income distribution.
