Effect of substrate concentration on enzyme activity essay - background an enzyme is a biological catalyst which speeds up biochemical reactions, such as digestion and respiration, but they remained unchanged at the end of the process (walpole, merson-davies, and dann 53. The effect of temperature on amylase activity our experiment demonstrated how different temperatures affected the rate of activity of amylase our results show that activity rate increases with temperature up to a certain point and then begins to decline. The effect of temperature on the activity of α-amylase was found to be maximum at 37 o c (figure 3) when compared to 35 o c as reported by vidyalakshmi et al, 2009 activity of α-amylase significantly decreased with the increase in the temperature beyond 37 o c.

The effect of temperature on α-amylase synthesis and secretion from barley (cv himalaya) half-seeds and aleurone layers is reported barley half-seeds incubated at 15 c in gibberellic acid (ga) concentrations of 05 and 5 micromolar for 16 hours do not release α-amylase. Amylase activity showed a slow rise for the first six days of imbibition, with a peak at 9 to 12 days, and a gradual decline until at least 15 days this pattern of alpha amylase activity paralleled that of starch break. Planning coursework- starch and amylase aim the aim of this coursework is to investigate the effect of temperature change, on the rate of hydrolysis of starch catalysed by amylase. The effect of ph on -amylase activity discussion the effect of temperature on enzyme activity enzymes are protein in nature the activity of enzyme and the rate of product formed will be maximum at the optimum temperature as temperature affects the speed of the molecules. The effects of temperature, ph, substrate concentration, and inhibitor concentration on the kinetics of amylase catalyzed reactions will be studied finally, the action of the amylase preparations isolated from microbial sources will be compared to that from human saliva.

Effect of temperature at dij’bent ph on catalase activity it has been shown by a number of investigators (michaelis and pechstein (l), sorensen (2), bodansky (3), morgulis (4). The optimal temperature of amylase would be 87°c because that’s the degree at which starch was broken down the fastest enzymes inside the body are said to function better at the optimal temperature of 37˚c, so the fact that our enzyme functioned better at 87˚c doesn’t support that. Temperature and ph are environmental factors that effect enzyme activity each enzyme has an optimum ph and temperature at which the reaction rate is greatest and the enzyme is most active amylase is an enzyme that can be found in the saliva of ones mouth.

These are the sources and citations used to research effect of temperature on amylase enzyme activity this bibliography was generated on cite this for me on monday, february 1, 2016. Effects of temperature, ph and substrate concentration on the kinetics of salivary alpha- amylase activity among cigarette smokers in awka, anambra state, nigeria. In order to see the effects of ph on enzyme action, you could substitute the change in temperature with the change in ph level i could use ph 4- 8 because ph 4 is an example of an acid, ph 7 because. Effect of temperature on amylase amylase is an enzyme that catalyzes the breakdown of starch, a polysaccharide, into maltose, a disaccharide this reaction is called hydrolysis, because a molecule of water is needed to break each bond. Effect of ph, temperature and metal ions on amylase activity from bacillus subtilis kcx 006 optimal temperature for amylase activity.

In this experiment, the enzymatic activity and specificity of salivary amylase was examined depending on the changes in ph and temperature in the first part of the experiment, the effect of temperature was determined, using constant temperature bath (4, room temp, 37, 50, 60, and 70°c. Temperature, ph, substrate and glucose on stability of α-amylase from bacillus licheniformis atcc 6346 to determine to determine the effect of temperature and ph on the stability of α-amylase this was pre-incubated at different temperatures and phs. Enzyme activity of salivary amylase page 3 label the first two columns with times from 0‐7 minutes (setting it on a piece of paper is a good way to do this. To study the effect of temperature on enzyme activity and to determine the optimum temperature principle: in any enzyme catalyze reaction the velocity increases with temperature till it reaches the maximum the velocity decreases with further increase of temperature this effect of temperature may be due to several reasons.

  • Effect of ph from the above results obtained on the effect of ph for the enzymatic activity of salivary amylase, we observed that the optimum ph on the enzymatic activity of salivary amylase is ph 7 this is because there is a theoretical prove that the positive test of salivary amylase on iodine is blue and only ph 7 showed positive test to that.
