What is the role of electrical force in chemical reaction?
The passage of an electric current through a conducting liquid causes chemical reactions.The resulting effects are called chemical effects of electric current
How does enzymes speed up chemical reactions?
The way enzymes speed up chemical/biochemical reactions is the same way that catalysts work. They provide an alternate pathway for the reaction which has a LOWER activation energy. They don't actually decrease the activation energy of the pathway in question, but rather they provide a different pathway that has a lower energy of activation.
Does a chemical reaction always require energy to start?
Yes, every chemical reaction requires activation energy, though in some cases the ambient heat of room temperature is enough to provide that energy.
How do enzymes speed up any metabolic activity?
They provide a route of lower activation energy, so the reaction is quicker because it doesn't need as much energy, (such as heat).
Speeds up or slows down a chemical reaction?
Raising the temperature of reactants will speed up a chemical reaction as it make the achievement of the Activation Energy easier. The temperature of individual atoms/molecules in a gas or liquid follow a normal distribution. Raising the temperature forces more atoms/molecules into the 'reaction worthy' side of the distribution.Sneeky energy pumping. Provide some kind of energy that doesn't raise the temperature but does break-down reactant into more reactive radicals. (light, electric discharge) See the photo-electric effectIntroduce enzymes. Chemicals that aren't consumed in the chemical reaction but provide a lower energy way for the reaction to proceed.Poisons react opposite to enzymes by inhibiting a lower energy alternative and forcing a higher energy path for the reaction.Take is easy,,,,,catalyst increase the rate of chemical reaction and inhibitor decrease it...

How enzymes works?
Provide an alternate pathway with a lower activation energy for a reaction
Does an enzyme lower the activation energy of a reaction?
ENZYMES WILL LOWER THE ACTIVATION ENERGY.ACTIVATION ENERGY IS THE INITIAL "PUSH" TO START A REACTION.ENZYME WILL SPEED UP THE PROCESS OF STARTING THE REACTION..THINK OF SOMEONE TRYING TO CLIMB OVER A WALL.THE WALL IS THE ACTIVATION ENERGY..ENZYME IS THE BULL DOZER THAT CRUMBLES THE WALL DOWN.THUS,YOU CAN QUICKLY GET OVER THE WALL.
What are the two kind of combustion?
Complete and incomplete. Combustion is a reaction, correct? Take this classic combustion reaction: CH4 + 5O2 -> 4CO2 + 2H2O. In technical terms, combustion is only complete if all the methane and all the oxygen are used up in the reaction. In practical terms we consider combustion complete if all the fuel gas converts to CO2, so we provide an excess of oxygen. There are two kinds of incomplete combustion. The first is when we provide enough oxygen to convert all the carbon to either CO or CO2. (We don't worry about the hydrogen - that element is so reactive it's going to grab oxygen first and leave the carbon to fend for itself.) The second is where we provide so little oxygen the carbon doesn't get a chance to react. This is where soot comes from.

How does an enzyme influence biological reaction?
All reactions, even exergonic, need an activation energy to happen. Enzymes provide that activation energy. Sometimes by their R groups, sometimes by stressing bonds in a molecule in their activation site and sometimes by only providing a space apart from the cytosol in their activation site for two substrates to react.

What types of energy can cause a chemical reaction to take place?
There are several sources of energy that could provide the activation energy needed for a chemical reaction to take place. Usually it is thermal energy, but photoexcitation (excitement by light energy) and electrochemical activation (excitement by electricity) are also commonly used.

What are facts about catalysts?
Some of the facts are: 1. Catalysts never get consumed in a reaction 2. Catalysts lower the activation energy of the reaction by providing an alternative path to it. 3. Some catalysts do not take part in reaction. They just provide surface or sites for the reaction to take place.
