STANDARD Zoology Factors affecting enzyme activity MCQ Question
The curve given below shows enzymatic activity in relation to three conditions (pH, temperature and substrate concentration). What do the two axes (X and Y) represent?
X-axis-Enzymatic activity Y-axis-pH
X-axis-Temperature Y-axis-Enzyme activity
X-axis-Substrate concentration Y-axis-Enzymatic activity
X-axis-Enzymatic activity Y-axis-Temperature
Correct Answer
Detailed Explanation
Enzymes generally function in a narrow range of temperature and pH. Each enzyme shows its highest activity at a particular temperature and pH called the optimum temperature and optimum pH. Activity declines both below and above the optimum values. X-axis always represents temperature or pH and Y axis represents enzyme activity.
