How might altering the pH affect the rate of the reaction?
Altering the pH might cause the enzymes involved in a reaction to be denatured. When enzymes are denatured, they do not function properly and the rate of the reaction either slows down or completely stops.
State one other factor apart from temperature that will affect the rate of reaction of amylase?
pH and temperature
What 2 conditions might change the rate of an enzymatic reaction?
pH and temperature
What can speed up an enzyme reaction?
An increase in temperature can increase the enzymatic reactions if it is not too hot and also if the pH is within the idea range it can speed up the reaction. The pH level is usually around 7 for most enzymes.
How does the reaction when blood pH is low compare to the reaction when blood pH is high?
We need to see what reaction that you are referring is.

Will enzyme activity be higher or lower if the pH is high?
Yes it does. Enzymes increase rate of reaction as the pH level increases but enzymes work best at optimum pH. If pH level still increase, then enzyme will become denatured and rate of reaction once again decreases.
How does pH influence the rate of enzyme reaction?
The optimum pH is that at which the reaction takes place quickest. A change in pH above or below this optimum denatures the enzyme (ultimately breaking hydrogen bonds that maintain the tertiary structure). This means that the rate is reduced as you change the pH, but not stopped totally as only some of the enzyme molecules are denatured.

What changes the rate of a reaction?
* Presence of enzyme * Change in pH * Change in temperature * Change in salt concentration.

How do you work out the rate of reaction when your independent variable is pH and your timing in seconds?
It is irrelevant what the independent variable is, whenever you work out rate of reaction you also divide 1 by the time in seconds. For example if it took 100 seconds your rate would be 0.01s-1.

We need to see what reaction that you are referring is.
Factors effecting catalase rate of reaction?
Temperature, pH, Substrate concentration, Enzyme concentration, Inhibitor concentration (ex. ammonia)
Is there any Procedure in enzyme and factors that affect enzyme activity?
pH, temperature, substrate concentration and enzyme concentration influences the rate of reaction
Do the presence of an enzyme catalyst will affect the time taken for a reaction to reach equilibrium?
An enzyme catalyst will lower the amount of energy required to preform a reaction. This in turn, will make it much easier for the reaction to start. So yes, it will let a reaction reach equilibrium quicker. Other factors affecting the time of reaction are: The concentration of the reactants, (the less volume and more pressure you have will increase the rate of reaction) The PH level (especially important for biology reactions, protein enzymes are built for specific PH levels and will not work correctly if they are in another PH level, buffers can be used to stabilize pH levels)
