The effects of temperature on enzyme activity the correlation of ph doesn’t seem as clear test tubes 2 and 3, which contained ph 5 and 6 starch, completed the. Enzymes work within an optimal temperature and optimal ph enzymes are highly specific for a single substrate the enzyme is usually much larger in size than the. Another reason is that our biology coursework help assistants have access to very credible resources they include substrate concentration, enzyme co-factors. Every biologist is familiar with the profile of the rate of an enzymatic reaction versus temperature as shown in the figure we know that enzymes from ecoli or warm-blooded animals tend to have an optimum around 37°c while those from thermal vent bacteria have much higher optimal temperatures.
What are enzymes enzymes belong to a class of molecules known as proteins, meaning they have one or more large chains of amino acids joined together by peptide bondsthe job of an enzyme is pretty specific: to catalyze, or speed up, chemical reactions by reducing the amount of energy needed for the reaction to take placein other words, the. Enzymes are generally used to remove toxins from animal bodies-which includes humans there are various factors that affect the rate of enzyme activity this lab investigates how temperature and substrate concentration effects enzyme activity rate this was tested by analyzing the change in enzyme.
This maximum is known as the temperature optimum of the enzyme in the above figure the temperature optima of three different enzymes is depicted you should note.

Temperature, ph and enzymes the activity of enzymes is affected by temperature and ph ph: scale of acidity/alkalinity ph below 7 = acidic, ph above 7 = alkaline temperature and enzymes. 4 how does the temperature affect enzyme function use evidence from your data from science 115 at elsinore high. Table 7: the absolute uncertainty for each temperature of lipase solution hence by changing the temperature of the lipase solutionthe change of rate of lipase activity would be measurable the temperature also effects the enzyme activity- most enzymes are mesophiles which have optimum temperatures of 20-40c the functions of enzymes. Each enzyme possesses a ph and a temperature optimum for its activity this optimum ph and temperature can be easily determined in the laboratory by carrying out the reaction in buffers over a wide range of ph or conducting tests at different temperatures enzymes demonstrate a rather high degree of specificity with respect to their substrates.
