Very high activation energy is needed in enzymelss reactions

∙ 14y agoNO reaction can take place at the absence of enzyme because that are the chemicals that help the reaction to happen.......EVen in our body the enzymes make the reaction to be happen

∙ 14y agoA reaction that doesn't involve an enzyme would take longer than one that used enzymes, and take more energy due to the increased time required to complete the reaction.
____________________
With an enzyme: the reaction takes less energy to start, and the reaction happens much faster. The reaction also reduces the amount of energy released.
Without an enzyme: The reaction is slow and takes more energy to start.
--------------------------------
Enzymes lower the activation energy of a reaction.
Each of the particles in a mixture has a given amount of kinetic energy, this average kinetic energy can be thought of as the temperature of the substance. Out of all the billions of particles, some will have enough energy to reach the reaction threshold due to the disorganized nature of distribution of kinetic energy between particles. A good way of thinking about this process would be to imagine a group of people holding volleyballs. Let the people represent the particles, and the volleyballs are units of kinetic energy. The people will pass the volleyballs randomly to other people directly next to them in the group. Some people will accumulate more volleyballs than others at first, but eventually they will all reach an equilibrium.
These particles will react with or without the enzyme present, but with the enzyme present the kinetic energy required to trigger all the particles to react within a certain amount of time is lowered. As an observer, you will see the reaction take place much faster with the enzyme than without.

What does Active Site mean?
The active site on an enzyme is the place where the enzyme binds the substrate and the chemical reaction takes place that changes the substrate(s) into the products of the reaction.
What is the three-dimensional part of an enzyme molecule where the reaction takes place?
Called the active site.
State the function of polar regions of amino acids on the active site of the enzyme?
The function of polar regions of amino acids on the active site of the enzyme is that it allows the reaction to take place more easily. The active site is the place where the actual chemical reaction takes place.
How does enzymes catalyze a chemical reaction?
by lowering activation energy to increase the reactionEnzymes are biological catalysts, and can hence lower the activation energy barrier of the reaction that it catalyses. Enzymes do this in several ways:1) Enzymes can provide a suitable environment for the reaction to take place. The active site of a enzyme can be highly acidic (pH
What is an anaerobic reaction?
it is a metabolic reaction which takes place in the absence of oxygen
What does Active Site mean?
The active site on an enzyme is the place where the enzyme binds the substrate and the chemical reaction takes place that changes the substrate(s) into the products of the reaction.
What is the three-dimensional part of an enzyme molecule where the reaction takes place?
Called the active site.
What the definition of Substrate?
The reactants of enzyme-catalyzed reactions. Or, A substance with which a enzyme binds itself and form a complex product, a chemical reaction takes place between enzyme and substrate.
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.
What is the difference a reaction without an enzyme and a reaction with an enzyme?
The speed at which the reaction takes place. Many reactions, especially exergonic reactions, would take place naturally, but too slowly to help living cells carry out the work they need to do. So enzymes lower the activation energy needed to start the reaction and these reactions in the cell are speed-ed up enough for cellular work to be done.
What is enzyme and active sites?
Enzymes are biochemical catalyst that are chemically proteins. Active site is a place where the enzymatic chemical reaction takes place.
State the function of polar regions of amino acids on the active site of the enzyme?
The function of polar regions of amino acids on the active site of the enzyme is that it allows the reaction to take place more easily. The active site is the place where the actual chemical reaction takes place.
Why would the reaction of a normal rate of an enzyme slow down and its substrate slow down when a competitive inhibitor is present?
because the competitive inhibitor stops the regular substrate from joining the enzyme. Its takes its place in the enzyme.
What substance takes place in an enzymatic reaction but does not change shape?
Enzymes. Substrates react with the active site of the enzyme and are broken down. Enzymes stay the same throughout the reaction.
In a chemical reaction a reactant binds to an enzyme at a region known as the?
In a chemical reaction, reactants bind to the enzyme at the active site. The active site is determined randomly each time a bond occurs.
Why is the active site on a cell important?
Active sites are located in enzymes inside the cells. this is where the substrate binds itself to the enzyme and the reaction takes place.
Were chemcal reaction takes place cell organelles?
chemical reaction takes place
