Wiki User
∙ 14y agoYes, enzymes act as catalysts and lower the amount of activation energy needed for the chemical reaction. They provide a 'different pathway' to the reaction.

How do enzymes affect the chemical reactions occurring in cells?
Enzymes are catalysts. They help lower the activation energy of reactions and increase the rate of the reaction. Without the help of enzymes, the biochemical reactions in the body would take so long that it would kill the person.
How subtstrates and enzymes fit together?
There are basically two theories to suggest how enzymes and substrates fit together. They are: The lock and key mechanism - this says that the structure of the substrate is exactly complimentary to the structure of the active site (i.e the region on the enzyme where the substrate fits/docks). The process is explained in terms of a lock and key analogy. The induced fit mechanism - this says that the active site of the enzyme is able to change its confirmatin (i.e 3D structure) slightly in order to accomodate the substrate.
Will a tiny little bit of an energy drink kill a rat?
A tiny little bit of energy drink will not kill a rat as they have similar bodies to humans. They are able to consume a majority of the same foods as people but at much lower quantities.
Which two factors determine how much energy an animal needs?
If the animal is endothermic or ectothermic and their size
What is the electric charge of a glow worm?
The Glow-Worm's GlowThe lamps of insects that produce light usually have a function in the insects' reproduction. Adults have an average life expectancy of only a month and, during that short time, they need to attract a mate and reproduce to form the next generation. The adult form eats only small amounts during its life, using the energy it has accumulated during its larval stage. It spends all of its time trying to attract a mate by flashing with its abdomen. Different species flash at different time intervals, so that each one can recognise the opposite sex of the correct species.One Thai species of gloworm uses the property of being able to synchronise the flashing of its light as a sign that it is a fit mate. Colonies of male glow worms collect together and start flashing to attract a mate. After a while the males adapt the frequency of their flashing to match those around it, and all of the colony flashes on and off at the same moment. The females chose their mates from the synchronised flashers at random but they avoid those that can't get their rhythm right as unsuitable fathers for their offspring.Glow worms (usually the larval stage but sometimes the adult females) glow (usually in the lower abdomen) through bioluminescence (a chemical reaction during which chemical energy is converted to light energy). The chemical reaction is very efficient with almost 100% of the energy turned into light (the best light-emitting diodes can only manage 22%).
What does an enzyme do to activation energy?
Enzymes generally lower the activation energy of a reaction, making them easier to take place.
What can speed up a reaction or lower the activation energy of a reaction and can digest things?
This would be an enzyme.
How enzyme accelerate metabolic reaction?
Enzymes lower the activation energy required to start the reaction.
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.
How does an enzyme catalyze a chemical reaction in regards to activation energy?
Any catalyst will make a chemical reaction easier or quicker to happen by lowering the activation energy. On a energy diagram, you will see a lower "hill" for activation energy, which corresponds to less energy required to begin the reaction.
How does does an enzyme reaction occur?
All reaction, regardless of being exergonic, need energy to complete/go through the reaction. Enzymes lower that activation energy.
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.
Enzymes work by lowering the what?
Also known as activation energy. threshold energy or you can also say enzymes lower the energy barrier
How does an enzyme help a reaction occur?
All reaction, regardless of being exergonic, need energy to complete/go through the reaction. Enzymes lower that activation energy.
Which molecules lower the activation energy?
Enzymes lower the activation energy of reactions.The activation energy of a reaction is the amount of energy that has to be put into the system before the reaction proceeds of its own accord. It is like setting fire to a log. First you must supply enough energy by burning a match, paper, kindling, and so on, until the log is hot enough to catch and continue burning on its own. This energy that you supply is the activation energy.When an enzyme is present, the activation energy is lower, and so the reaction proceeds more readily at the temperature of the organism. A concept known as the induced-fit modelexplains how enzymes lower activation energy, by suggesting that the interaction of a substrate with an active site on the surface of the enzyme causes a change in the enzyme's shape, which in turn affects the substrate in such a way as to encourage the reaction.
Is more energy required for a chemical reaction in the absence of an enzyme?
Without an enzyme, the activation energy needed to start a reaction is much greater. An enzyme is a catalyst, which decreases the amount of activation energy needed to start a reaction. By doing so, it decreases the amount of time the chemical reaction takes place.
How do enzymes speed up chemical reactions?
Enzymes lower the activation energy of a chemical reaction.
