Which of the following statements is incorrect regarding enzymatic act...
Every enzyme posses an optimum pH value where it is most effective. Most enzymes show maximum activity in a pH rang of about 6.0 to 7.5 i.e, near neutra pH. Some digestive enzymes have their optimum pH in the acidic or alkaline range. E.g., pepsin of gastic juice has its optimum at pH 2 (acidic) whereas typsin of pancreatic juice shows maximum activity at pH 8.8 (alkaline). A rise and fall in pH reduces enzyme activity by changing the degree of ionisation of its side chain.

Which of the following statements is incorrect regarding enzymatic act...
Enzymatic activity refers to the rate at which an enzyme catalyzes a specific reaction. The correct statement regarding enzymatic activity is:
a) It increases with increase in substrate concentration up to the saturation point: The rate of reaction increases as the substrate concentration increases until the enzyme becomes saturated with substrate molecules.
b) It is highest at optimum pH value: Each enzyme has a specific pH range at which it functions optimally. Any deviation from this pH range can affect the enzyme's activity.
c) It initially decreases with an increase in pH value: This statement is incorrect. Enzymes have an optimal pH range, and any deviation from this range can affect the enzyme's activity. However, the activity does not initially decrease with an increase in pH value.
d) It initially increases with an increase in temperature and then decreases: Each enzyme has an optimal temperature range at which it functions optimally. However, at temperatures above the optimal range, the enzyme's activity decreases due to denaturation.
In summary, option C is incorrect regarding enzymatic activity. The correct statement is that enzymatic activity initially increases with an increase in temperature and then decreases.
a) It increases with increase in substrate concentration up to the saturation point: The rate of reaction increases as the substrate concentration increases until the enzyme becomes saturated with substrate molecules.
b) It is highest at optimum pH value: Each enzyme has a specific pH range at which it functions optimally. Any deviation from this pH range can affect the enzyme's activity.
c) It initially decreases with an increase in pH value: This statement is incorrect. Enzymes have an optimal pH range, and any deviation from this range can affect the enzyme's activity. However, the activity does not initially decrease with an increase in pH value.
d) It initially increases with an increase in temperature and then decreases: Each enzyme has an optimal temperature range at which it functions optimally. However, at temperatures above the optimal range, the enzyme's activity decreases due to denaturation.
In summary, option C is incorrect regarding enzymatic activity. The correct statement is that enzymatic activity initially increases with an increase in temperature and then decreases.
