Week 2 – Effect of Enzyme & Substrate Concentration on

Enzyme assay Wikipedia. This means that the more substrate there is, the more enzyme activity can be observed. However, the effect of substrate on enzyme activity is not simply to increase it. Substrate concentration has many different effects on enzyme activity, depending on the context of the reaction and the nature of the enzyme. Substrates increase enzyme activity, When substrate concentration is high, the substrate-enzyme interaction can be more complicated. In this case, substrates are competing for the active site or enzyme. Depending on the molecular structure of the enzyme, the catalytic rate can be influenced by the substrate concentration in different ways..

Research Question: How does the concentration change in the starch (substrate) effect the reaction rate of amylase (enzyme) ? Background Information: The Effect of Substrate Concentration on Enzyme Activity Background Hydrogen peroxide is a toxic waste product formed as a result of metabolic reactions in cells. The enzyme catalase catalyses the breakdown of hydrogen peroxide (H 2 O 2) into water and oxygen. Potato extract can be used as a source of the catalase enzyme. Introduction

After this point, increases in substrate concentration will not increase the velocity (delta A/delta T). This is represented graphically in Figure 8. It is theorized that when this maximum velocity had been reached, all of the available enzyme has been converted to ES, the enzyme substrate complex. This point on the graph is designated Vmax When substrate concentration is high, the substrate-enzyme interaction can be more complicated. In this case, substrates are competing for the active site or enzyme. Depending on the molecular structure of the enzyme, the catalytic rate can be influenced by the substrate concentration in different ways.

Objective: To analyze the effect of substrate concentration on the activity of enzymes. Theory: Enzymes are protein molecules that act as biological catalysts by increasing the rate of reactions without changing the overall process. If more substrate is present than enzyme, all of the enzyme binding sites will have substrate bound, and further increases in substrate concentration cannot increase the rate. The activity will decrease; a pH of 6.3 is more acidic than 7.4, and one or more key groups in the active site may bind a hydrogen ion, changing the charge on that group.

When substrate concentration is high, the substrate-enzyme interaction can be more complicated. In this case, substrates are competing for the active site or enzyme. Depending on the molecular structure of the enzyme, the catalytic rate can be influenced by the substrate concentration in different ways. It is always best to check the enzyme activity in advance. In the ICT support there is a datalogging sheet on monitoring an enzyme-catalysed reaction. The Core Practical requires investigation of enzyme and substrate concentration. Having completed the practical investigating enzyme concentration, students can plan how to investigate substrate concentration, which would use a similar procedure

As a result enzyme-substrate complexes form more quickly and the rate of reaction increases. However, there is a limit as eventually there all the enzyme active sites are already occupied with substrate - the enzyme '''active sites become saturated'''. Any further increase in substrate concentration has no further effect on the reaction rate The six factors are: (1) Concentration of Enzyme (2) Concentration of Substrate (3) Effect of Temperature (4) Effect of pH (5) Effect of Product Concentration and (6) Effect of Activators. The contact between the enzyme and substrate is the most essential pre-requisite for enzyme activity.
