BIOMOLECULES AND ENZYMES

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: -When the temperature is increased, the average velocity of the particles is increased. The average kinetic energy of these particles is also increased. The result is that the particles will collide more frequently, because the particles move around faster and will encounter more reactant particles.

Detailed explanation-3: -An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision (Figure.

Detailed explanation-4: -Because the speed of a particle is proportional to the square root of its kinetic energy, increasing the temperature will also increase the number of collisions between molecules per unit time.

Detailed explanation-5: -With increase in the temperature, the number of molecules with energy equal to or greater than activation energy increases. This increases the number of effective collisions and the rate of the reaction.
