To investigate the effect of effect of temperature on enzyme activity graph on enzyme activity. The enzyme catalyse is a biological enzyme. Hydrogen Peroxide, which is harmful. This means that the active site will be changed. Get feedback on grammar, clarity, concision and logic instantly.

The Effect of Temperature on Enzyme Activity. The first way is by helping the substrates to bind together. It is easier for substrates to react if they are closer together, thus bringing on the transition state. The second way is by repositioning them. Substrates do not travel in a particular direction and so if they are repositioned so that they collide, they will react. Another way to cause reactions is using an induced-fit model.

This means that the enzyme changes its shape to better fit the substrate and make for a stronger bond. Finally stopping water molecules from getting through and disrupting the reactions will help binding occur. Problem Question What is the effect of the substrate concentration on enzyme activity. Hypothesis As the concentration of the substrate increases, the rate of reaction also increases until it reaches its maximum point where all enzyme molecules are already active due to the solution becomes saturated with the hydrogen peroxide. An enzyme is a type of protein found in all living cells. It is composed of polymers of amino acids.

An enzyme is affected by how much acid or alkali is present. The plot of enzyme activity Vs. H is often “bell shaped” since two different amino acid groups of the enzyme are being titrated to different states of ionization at the different pH values. H values above the pK, the enzyme will be most active. Therefore, the rate of reaction increases.

45ºC the human enzymes will denature. This also supports the prediction. 100 cubic centimetre measuring tube. C and at room temperature. H 7 buffer and catalyse will be used.
