What describes the energy of activation?
Activation energy is the least amount of energy needed to start a chemical reaction. It is used to activate atoms or molecules in order for them to begin a chemical reaction.
Which molecules facilitate chemical reactions in the body by reducing the reaction's activation energy?
Enzymes
Molecules involved in a chemical reaction must collide to react What is this concept called?
Collision Theroy
How can activation energy be reduced?
Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of reaction.
How does the additions of a catalyst affect the energy of activation of a chemical reaction?
A catalyst changes the reaction mechanism to one with a lower activation energy; activation energy is lowered when a catalyst is added
What is an activation site?
An active or activation site is a small opening in an enzyme where substrate molecules are bound, and go through a chemical reaction. This reaction is caused by the collision a substrate that slots into the active site of the enzyme.

Why don't all collisions between reactant molecules lead to product formation?
For most reactions, chemical reaction requires that molecules acquire greater than average energy. This is called the "activation energy", and only some collisions impart a sufficient amount of energy.
Which group of biological molecules can speed up chemical reactions by lowering a reaction's activation energy?
Enzymes
How do enzymes function speeding up in a chemical reaction?
Enzymes lower the activation energy of a chemical reaction. Since more molecules have sufficient energy to react, the reaction occurs faster.
Why does heat speed up a chemical reaction?
It provides energy to overcome the activation energy.
What speeds up chemical reaction by lowering activation energy?
Enzymes are the molecules that speed up chemical reactions, and these are forms of catalysts.
How can activation energy be reduced?
Allows more molecules to overcome the activation enthalpy, so there are more molecules available to collide with each other, increasing the chance of a successful collision, increasing the number of collisions per second and with it the rate of reaction.
Energy is the energy needed to start a chemical reaction?
The energy needed to statr a chemical reaction is the 'Activation Energy' , which is given the symbol (Ea).
Nitrogen Oxide and ozone sometimes react to produce nitrogen dioxide and oxygen The collision between the two molecules does not always lead to a reaction Explain why?
Activation energy. Intermediary molecules (catalysts) required.
