How do enzymes affect activation energy and reaction temperature?

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.

What is activation energy and how do enzymes effect it?
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.
Enzymes increase the rate of a reaction by doing what?
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.
How do enzymes affect the activation of energy in chemical reactions?
they lower the activation energy.
What is the effect that enzymes have on certain chemical reactions in living things?
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.
How do enzymes affect reactions?
The initial velocity of a gradually increases during enzyme substrate reaction. The concentration of the substrate also increases with it.
Enzymes affect the reactions in living cells by lowering the?
activation energy of the reaction.
How do changed in temperature and activation energy compare in how they affect reaction rate?
Changes in temperature and activation energy have opposite effects on reaction rate.
How do changes in temperature and activation energy compare in how they affect reaction rate Apex?
Changes in temperature and activation energy have opposite effects on reaction rate.

What affect rates does a enzyme catalyzed reaction have?
Enzymes increase the rate of reaction by changing the reaction mechanism to one with a lower activation energy.
How do enzymes affect the way chemicals react?
They lower the activation energy needed to start a chemical reaction.
Enzymes increase the rate of a reaction by doing what?
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.
How do enzymes affect the rate of reaction?
Enzymes speed up a reaction but they are not changed by the reaction. They are a protein molecule that helps other organic molecules enter into chemical reactions with one another but is itself unaffected by these reactions. In other words, enzymes act as catalysts for organic biochemical reactions.
How does the presence of enzymes affect the equilibrium position of the breakdown of carbohydrate into glucose?
Enzymes cannot affect the equilibrium of a reaction, nor can they cause a thermodynamically unfavorable reaction to proceed. They are catalysts and can only alter the activation energy and therefore the rate of the reaction.
How do enzymes affect the activation of energy in chemical reactions?
they lower the activation energy.
How does activation energy affect the progress affect the progress of a reaction?
The reaction will not occur unless the activation energy is met.
What is the effect that enzymes have on certain chemical reactions in living things?
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.
