Ideally the reaction should take about 60 seconds at this pH: this is the usual optimum for amylase (see note 1). If the reaction is too fast, either reduce the ...

For each pH investigated, record the time taken for the disappearance of starch, eg when the iodine solution in the spotting tile remains orange-brown. Hazards ...

The enzyme amylase breaks down starch into glucose. If the enzyme is working effectively, this will happen quickly. At pH 7 it took the shortest time before the ...

4 нояб. 2024 г. · The effect of different pH levels on the activity of amylase can be investigated. Apparatus. Spotting tile. Measuring cylinder. Test Tube.

GCSE Biology required practical to investigate the effect of pH on amylase. The experiment investigates how enzyme activity is affected by pH. Shop our full ...

Theoretically, alpha-amylase will reach its highest enzyme activity closer to pH 7. Initially, to determine the rate of reaction, a test was completed on ...

There was an increase in α-amylase activity with increasing pH from 5 to 7. Maximum amylase activity was recorded at pH 7 and it declined with further increase ...

pH affects enzyme reactions because it affects the detailed structure of the active site of the enzyme. Amino acids (which make up proteins) are strongly ...

22 окт. 2024 г. · α-Amylase activity increased from pH 3.0 and peaked at pH 6.0-8.0 beyond which it gradually decreased until pH 10.0. CM- cellulase activity ...
