Temperature Effect | MCQs

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.

Explanation

Explanation

Changes in pH can cause enzymes to denature, losing their native structure and activity.

This is because enzymes are highly specific to their optimal pH range.

Changes in pH can disrupt the delicate balance of charges and hydrogen bonds that maintain the enzyme's active structure.

Explanation

 Le Chatelier's principle states that when a system at equilibrium is subjected to a change (like temperature), the system will shift to counteract the change and re-establish a new equilibrium. 

Explanation

 With a temperature rise, the velocity of sound increases.

This is because warmer temperatures cause molecules to move faster, allowing sound waves to propagate more quickly through the medium

Specifically, the speed of sound is directly proportional to the square root of the absolute temperature.

For every degree Celsius increase in temperature, the speed of sound in air increases by approximately 0.6 m/s
