Question

What are the effects of pH, temperature, enzyme concentration and presence of inhibitors on the activity of the enzymes?

Answer 1

Answer:

Effect of pH on enzyme activity

• Enzyme activity is very poor at very low and high pH.
• Enzyme activity increases with increasing pH up to optimum pH value. Then activity decrease with increasing pH.

Effect of temperature on enzyme activity

• Enzyme activity is increased with temperature up to certain limits. Most enzyme activities increased by 50-100% as Temperature rise in 10 ⁰cel. After temperature limits enzyme decomposed and enzyme activity vanishes.

Effect of Enzyme concentration on Enzyme activity

• Enzyme activity is increased with concentration until the reaction gets the maximum rate. Once reaction attain maximum rate, further addition of enzyme will not increase the rate of reaction.

Effect of inhibitors on enzyme activity

• inhibitors is used to slows down the reaction. Hence, the presence of inhibitors in the enzyme will surely decrease enzyme activity.
