When temperature rises above the optimum temperature, the rate of reaction decreases rapidly due to _____?
جب درجہ حرارت زیادہ سے زیادہ درجہ حرارت سے بڑھ جاتا ہے تو ، _____ کی وجہ سے رد عمل کی شرح تیزی سے کم ہوجاتی ہے؟
Answer: Enzyme denaturation
Explanation
At temperatures above the optimum, enzymes lose their three-dimensional shape — a process called denaturation.
Denatured enzymes cannot bind substrates properly, leading to a rapid drop in reaction rate.
