As kinetic energy, and therefore temperature increases, the number of effective collisions which result in sufficient activation energy also increases, which is why reactions happen at a faster rate at higher temperatures.
Enzymes lower the activation energy required for a chemical reaction to occur by providing an alternative pathway for the reaction to proceed. This facilitates the reaction to occur more readily and at a faster rate. Ultimately, enzymes speed up the reaction by lowering the energy barrier that needs to be overcome.
An enzyme is a catalyst that speeds up a chemical reaction. It functions by lowering the activation energy required for a reaction to occur, and by reducing the activation energy, the reaction speeds up.
There is no straight forward relation between enzyme and activation energy because although energy of reaction is fixed and is governed by laws of chemistry but for biochemical reactions concentration of enzyme and conc. of substrate affect rate of reaction and energy, but in general enzymes decrease activation energy of reaction.
Energy activation, often in the form of heat, helps enzymes overcome the activation energy barrier required for a chemical reaction to occur. By providing the necessary energy, activation helps enzymes facilitate reactions at a faster rate. Without sufficient activation energy, enzymes may not function optimally or the reaction may not proceed efficiently.
Enzymes lower the activation energy (or free energy of activation for the very scientific) of the chemical reactions they catalyse. The enzymes can make a reaction proceed much more quickly than it otherwise would by astronomical figures, e.g. 109 times! Enzymes don't affect the equilibrium position, but they do affect the rate.

Changes in temperature and activation energy have opposite effects on reaction rate.

False. Enzymes do not affect the thermodynamics of a reaction. They only lower the activation energy required for the reaction to proceed, thereby increasing the rate of the reaction without changing the equilibrium constant or overall energetics of the reaction.
They lower the activation energy needed to start a chemical reaction.

Enzyme-catalyzed reactions generally increase the rate of a reaction by lowering the activation energy required for the reaction to occur. Enzymes do this by stabilizing the transition state of the reaction, allowing it to proceed more easily and quickly. Additionally, enzymes can enhance reaction specificity and selectivity, making them very efficient catalysts.
Changes in temperature and activation energy have opposite effects on reaction rate.
The reaction will not occur unless the activation energy is met.
Energy activation, often in the form of heat, helps enzymes overcome the activation energy barrier required for a chemical reaction to occur. By providing the necessary energy, activation helps enzymes facilitate reactions at a faster rate. Without sufficient activation energy, enzymes may not function optimally or the reaction may not proceed efficiently.
Enzymes can lower the activation energy required for a reaction to occur, making the reaction proceed faster, but they do not affect the equilibrium of the reaction. Enzymes can facilitate both forward and reverse reactions depending on the conditions and the concentration of the reactants and products.
