Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

An investigation into the effects of sugar concentration on yeast activity Introduction: Yeasts are eukaryotic micro organisms belonging to the kingdom fungi. Yeasts live on sugars and produce ethanol and carbon dioxide as by-products. [James Mallory‚ 1984]When Yeasts are given water and sucrose they convert the sucrose into glucose then convert the glucose into carbon dioxide and ethanol following the following reaction: C₆H₁₂O₆ ( 2(C₂H₅OH + CO₂ [Brady Burkhart‚ Terrell Grayson and Eric Kimler

The Effect Of Substrate Concentration On The Activity Of The Enzyme Catalase A Level Biology Project Aims This is an experiment to examine how the concentration of the substrate hydrogen peroxide affects the rate of reaction of the enzyme catalase. Background Information Enzymes such as Catalase are protein molecules which are found in living cells. They are used to speed up specific reactions in the cells. They are all very specific as each enzyme just performs one particular reaction. Catalase

Lab Report (Effect of concentration on enzyme activity) Biology Noor Alawadhi 11- KC Introduction: An Enzyme is a protein‚ which is capable of starting a chemical reaction‚ which involves the formation or breakage of chemical bonds. A substrate is the surface or material on or from which an organism lives‚ grows‚ or obtains its nourishment. In this case it is hydrogen peroxide. This lab report will be explaining the experiment held to understand the effects of the changes in the amount of

potatoes and different sucrose concentrations (0.15‚ 0.20‚ 0.25‚ 0.30‚ 0.35 and 0.50). It was expected that the potatoes would lose weight as the potatoes would have lower water potential when placed in a solution ‚ and in this can be taken from the theory of osmosis which states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn‚ 2009)‚ moving water from a high to a low concentration‚ so in this case water would

Background Information: Enzymes such as catalase are globular protein molecules with catalytic properties. A catalyst is a substrate which can alter the rate of reaction without itself undergoing any permanent change. As they are not changed

Describe how igneous activity can affect the landscape Igneous intrusions form when cooling‚ crystallization and loss of gases cause a once fluid magma to solidify. Most rocks that form intrusions originate as either granitic or basaltic magma. Granitic magmas are low density and small quantities‚ just a few kilometers wide‚ rise slowly through the earth’s upper crust‚ pushing existing country rock aside. However‚ very large granite masses‚ which can be up to 1‚000 times larger‚ are formed when magma

pH on enzyme activity in skeletal muscle‚ particularly the activity of lactate dehydrogenase (LDH). LDH is a glycolytic enzyme which converts pyruvate to lactate in the following equation: LDH Pyruvate+ NADH ------------ Lactate + NAD The reaction above can move in both directions‚ forward (favored by Type II skeletal muscle) and reverse (favored by Type I skeletal muscle and the heart)
