The ideal pH for water is perfectly neutral, or a reading of 7.
6
PH 9
Optimum pH of most enzymes is 7. Optimum pH is pH at which enzyme shows maximum activity .It all depends to the particular enzyme you are talking about, there is no general rule. for example in human pepsin catalyse the reaction at high acidic pH (1.5 to 3) whereas trypsin has optimum pH falls between 7 to 9 (neutral to basic).
The optimum pH is 8.8
PH 9
pH7
The optimum pH is neutral, 7.
The optimum pH of lactase is pH = 6.5.
The temperature optimum can be affected by pH if the pH chosen for a particular experiment deviates from the pH optimum for invertase
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
That is a short form of "optimum pH level", the point where an enzyme is most active. The optimum pH value varies greatly from one enzyme to another. Extremely high or low pH generally results in complete loss of activity for most enzymes.
The optimum pH of salivary amylase is 6.8 (slightly acidic).
