What kind of chemical reaction needs a constant supply of energy?
Wiki User
∙ 9y ago
If a reaction requires a constant input of energy, the products are higher in energy than the reactants. This type of reaction is known as endothermic, since it involves an increase in energy of the system. Conversely, reactions that release energy are known as exothermic.

How important are chemical bonds in metabolism?
Chemical bonds are broken to supply us with energy. Without bonds, and our ability to break them, the food we eat would not supply us with energy.
Because it cannot be recycled ecosystem need a constant supply of?
Energy
How much heat does a reaction produce?
The amount of heat produced in a reaction is not fixed. It depends upon the total amount of energy change that has taken place in the reaction altogether. Not only this, all reactions do not produce heat. In some cases we have to supply energy from external sources to get the reaction started.
What substance needs to be maintained to give cells a constant supply of energy?
oxygen and glucose
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.
In a chemical reaction what does it take energy to do?
For most chemical reactions, energy is required to supply an "activation energy" required before reaction.
Why does an organism need energy and constant supply of energy?
An organism needs energy and constant supply of materials to grow and develop.
Why does an organism need energy and constant supply of materials?
An organism needs energy and constant supply of materials to grow and develop.
Do enzymes work by providing energy to initiate reaction?
No they do not supply energy to start a chemical reaction, however energy has something to do with it. Enzymes actually lower energy barriers, in other words it reduces the activation energy needed which is the energy absorbed before the chemical reaction can start.
What are the reactants in this reaction?
Almost certainly the ones on the left side of the arrow (or on the bottom of the equilibrium constant expression). However, since you neglected to supply "this chemical reaction", we can't give you a better answer than that.
Why fire is burning up?
First of all the fire that you see is just the light emitted by a chemical reaction called oxidation. This reaction consumes energy, in the form of oxygen and a flammable material such as wood. If either one runs out the fire dies. So in short, fire requires a constant supply of energy and that runs out so fire 'burns up'.
Which of these changes needs you to supply energy?
chemical energy
What does Earth receives a constant supply of?
light energy
What does chemical energy mean in physics?
chemical energy,Energy stored in the bonds of chemical compounds. Chemical energy may be released during a chemical reaction, often in the form of heat; such reactions are called exothermic. Reactions that require an input of heat to proceed may store some of that energy as chemical energy in newly formed bonds. The chemical energy in food is converted by the body into mechanical energy and heat. The chemical energy in coal is converted into electrical energy at a power plant. The chemical energy in a battery can also supply electrical power by means of electrolysis.

How might you cause an edothermic chemical change to begin and keep going?
By supplying energy to it.Explanation:Since an endothermic reaction, by definition, NEEDS energy to go on, it will cool down (= taking heat energy from the reactants). It will stop itself as any reaction will slow down at lower(ing) temperatures.So SUPPLY of heat is at least necessary to KEEP temperature at its minimum level of 'ongoing' reaction.
