The rate of enzyme activity is at its highest when the temperature is 45°C. Thus option C is correct.
What are the factors affecting enzyme activity ?
The optimum temperature for most of the enzymes is between 25-35°C and above 50°C leads to destruction of enzymes
The rate also increases with increased enzyme concentration up to the saturation point
Enzymes work at their optimum pH. The rate of enzymatic reaction depend on substrate concentration.
The accumulation of the products decreases the activity of enzymes, as they combine with the active site of enzymes by forming a loose complex and inhibits the activity of enzymes.
Some chemical substances like co-factors, potassium ion (K⁺), manganese ion (Mn²⁺) can increases the enzyme activity.
water increases the reaction rate. Light increases the reaction rate in some enzymes but harmful radiation like UV rays and X-rays decreases activity.
