LIFE SCIENCE

Detailed explanation-1: -Higher temperature generally causes more collisions among the molecules and therefore increases the rate of a reaction. More collisions increase the likelihood that substrate will collide with the active site of the enzyme, thus increasing the rate of an enzyme-catalyzed reaction.

Detailed explanation-2: -As the temperature increases so does the rate of enzyme activity. An optimum activity is reached at the enzyme’s optimum temperature. A continued increase in temperature results in a sharp decrease in activity as the enzyme’s active site changes shape. It is now denatured.

Detailed explanation-3: -Kinetic Energy and Internal Energy With faster velocities, there will be less time between collisions. This results in more molecules reaching the activation energy, which increases the rate of the reactions. Since the molecules are also moving faster, collisions between enzymes and substrates also increase.

Detailed explanation-4: -Answer. As temperature increases, the kinetic energy contained within substrate and enzyme molecules also increases. This means that they move faster, and the substrates are more likely to successfully collide with the enzyme’s active site.
