PH 9
The optimum pH of lactase is pH = 6.5.
The data indicates that the optimum substrate concentration for the lactase-catalyzed reaction is typically at a concentration where the enzyme active sites are mostly saturated with substrate molecules, leading to maximum reaction rate. Beyond this point, increasing substrate concentration may not significantly increase the reaction rate due to enzyme saturation. This optimum concentration ensures efficient enzyme-substrate binding and catalytic activity.
The data suggests that the enzyme-catalyzed reaction has an optimum pH level at which it functions most efficiently. This pH level is where the enzyme's activity and stability are maximized, leading to the highest reaction rate. Deviating from this optimum pH can result in decreased enzyme activity and potentially denaturation.

The optimum pH level for lactase, the enzyme that breaks down lactose, is around 6.5 to 7.5. This pH range allows for optimal activity of the enzyme, leading to efficient breakdown of lactose into glucose and galactose. Deviation from this pH range can reduce the effectiveness of lactase in digesting lactose.
Exactly. If a reaction is going as fast as it can go (optimum) and you add an inhibitor (something to impede it) it slows down. This could be done to prevent excessive heat or too much gas at one time.
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
it generally helps because the temperature is the average kenetic engergy. that means that the substrates and enzymes can move faster and spread more quickly. the only problem is that enzymes can denature at higher temperatures. this means that at so high of temperature the enzymes lose their shape and then they can't bond to the substrates to catalyse the reaction.
At optimum pH, enzymes and biological processes function at their maximum efficiency. This is because the pH affects the charge on amino acid side chains in proteins, which in turn can affect their structure and activity. Maintaining the optimum pH is crucial for proper functioning of biological systems.
Pepsin is therefore acidic since the pH in the stomach is 2
The optimum temperature for the enzyme polyphenol oxidase (PPO) is 40 degrees Celsius. This is the temperature at which the enzyme is most effective; like many other enzymes the rate of reaction will decrease with temperature, but if the temperature rises much above the optimum level, it will cause the enzymes to denature. Denatured enzymes will stay denatured even if the temperature decreases again. The optimum pH for polyphenol oxidase is 5.
Increasing the temperature increases the rate of an enzymeÊcontrol reaction up to a certainÊ optimum level, where further increase causesÊ the rate of reaction to fall sharply. This is because enzymesÊhave optimum temperatures on which they work well, andÊ they are denatured when their optimum temperatures are exceeded.
