What kind of chemical reaction needs a constant supply of energy?
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.
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.
Glycerinated muscle requires the addition of what molecule to supply the energy for muscle contraction?
ATP
How do you supply activation energy begin a reaction?
Generally, the activation energy is given by heat, so, you must watch carefully the temperature of the reaction, because you can get undesired products in the reaction, or yielding nothing at all.
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'.
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.
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.

What is the term for the energy responsible for the variations in the reaction rates of chemical processes?
It's hard to know precisely what is meant by this question. You may be thinking of activation energy, the minimum energy needed to start the reaction, which explains why one reaction may go at a different speed from another. On the other hand, if you are thinking of just one reaction going faster and slower depending on the energy supply, then that's most often thermal energy.
What is the concept of the dark reaction as it relates to photosynthesis?
The dark reaction as it pertains to photosynthesis occurs when the plant, in the absence of sunlight, continue to supply energy. The dark side of photosynthesis relies upon the stored starches to fuel the energy cycles.
Which electrical test requires the supply to be energized?
Testing of an electrical circuit for voltage requires the supply to be energized.
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 type of potential energy can be burned to supply heat?
a log or even a gasoline soaked cloth. anything that is capable of possessing energy like a rubber band.
