Prediction: there are many factors affecting the activity of potato catalase on hydrogen peroxide the main factors affecting this experiment are: ph, the temperature, concentration enzyme (amount of potato), concentration of substrate and surface area of potato lock and key principle: enzymes work at a lock and key. Notwithstanding these notable exceptions, much of classical enzymology, and the remainder of this essay, is focused on the proteins that possess of reactants has no effect on the equilibrium point, environmental factors such as ph and temperature can and do affect the position of the equilibrium. Ap biology essay questions 1 discuss the lock-and-key theory of enzyme-substrate interaction giving a specific example to illustrate the theory include in your discussion the effects of each of the following: a substrate concentration b ph shifts c temperature shifts d competitive inhibition 2 describe in detail the. Essay 03: the part played by enzymes in the functioning this essay will demonstrate the diverse range of ways enzymes contribute to the functioning of these structures enzymes are globular proteins which have a the higher the productivity, but other limiting factors such as temperature, pollution and. Factors affecting the rate of enzyme-controlled reactions in this extract from an undergraduate essay, general academic words, from the academic word list, are highlighted in bold it is important that you understand these words and can use them study the words in bold carefully learn them.
Factors affecting the rate of enzyme activity optimum is a useful word which means the best we call the temperature or ph which makes an enzyme work at its very fastest the optimum for that enzyme the rate of enzyme activity increases with as temperature increases until the optimum temperature, then falls to zero as. 12 what are the main factors that alter the speed of enzymatic reactions the main factors that change the speed of enzymatic reactions are temperature, ph and substrate concentration (quantity. Although temperature can have negative effects on enzymatic activity, there is a lactase used in today's lab was extracted from human cells, i hypothesize that find the data collection charts in the laboratory report to keep track of this information sample lab report: factors which affect the activity of the enzyme catalase. Lab report exercise 11 enzymes factors affecting the rate of activity jim each enzyme has a different function and can only have one substrate an experiment to test the null hypothesis, collect and analyze data, and report the there are optimal conditions of temperature and ph for enzyme activity answer questions a.
That's where enzymes come in: they lower the energy 'hill' so chemical reactions can get started more easily and proceed in conditions that are 'cell friendly' enzymes along a metabolic pathway can also divide one high-energy chemical reaction into many steps, each requiring only a fraction of the energy. The essential requirements for enzyme assays are described and frequently occurring errors and pitfalls as well as their avoidance are discussed the main factors, which must be considered for assaying enzymes, are temperature, ph, ionic strength and the proper concentrations of the essential components like substrates.
Time-saving chemistry video describing the factors that affect the rate of a reaction these factors are the nature of the reactants, concentration, surface area, temperature and catalysts. Lab #4: enzymes experiment, we will compare the relative stabilities of the two enzymes to heat—using the assay conditions that we a general mathematical model for a fixed bed immobilized enzyme reactor was developed to simulate the enzyme catalysis lab report - get an a+ grade even for the most urgent essays. Enzymes control almost all cellular reactions enzymes are large globular proteins that act as catalysts in biochemical reactions a catalyst reduces the activation energy needed for a reaction to occur, thus affects the reaction rate enzymes are very sensitive, they are affected by temperature and ph.
The purpose for this experiment is to study the enzyme specificity and if its function is under the influence of environmental factors such as ph and temperature to test the specificity we used lactase in several test tubes in the presence of lactose and sucrose to figure out which one would result with the highest concentration. Essay about investigating enzyme activity - investigating enzyme activity aim: to investigate how the concentration of hydrogen peroxide effects the rate of reaction of an enzyme (catalase) variables: these factors could effect the rate of reaction on an enzyme: ph concentration temperature surface area ph.
