Question

The curve given here shows enzymatic activity with relation to three conditions ( pH , temperature and substrate concentration)

What do the two axises (x and y) represent ?

	X - axis	Y -axis
A	Substrate concentration	Enzymatic activity
B	Enzymatic activity	Temperature
C	Enzymatic activity	pH
D	Temperature	Enzymatic activity

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer: (D)

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.
