Why do enzymes serve as a place where a chemical reaction can occur?
enzymes contain specific active site complimentary to certain molecules. they speed up the reaction by decreasing the activation energy.
What is necessary for evaporation to occur?
Heat, or energy, is needed for evaporation to occur. Energy breaks bonds holding water molecules together, making evaporation possible.
What is a chemical reaction that breaks down compounds into simpler products?
When chemicals are combined or broken down, they go through reactions. The combination is called a synthesis reaction and breaking down is called a decomposition reaction.
A collision may have energy in excess of the activation energy reaction may not occur?
"Collisions may have enough energy to react yet not react if the orientation of the molecules is incorrect. Difficult to explain here without graphics, but basically of the molecules are facing the wrong way it won't happen."
Why does increasing the temperature of a reaction increase its rate?
It provides energy to overcome the activation energy.
Do molecules need to collide for a chemical reaction to occur?
Yes, it is true.
Is ATP needed for translation to occur?
It provides the energy necessary for the reaction to occur.
What type of reaction occur when atoms combine to form molecules or when molecules break down into atom?
Chemical reactions.
Why does concentration of a reactant influence the reaction rate?
Oxygen!
What are the substances that are added to a reaction speed up the reaction?
Catalysts. They lower the amount of energy needed for the reaction to occur.
The amount of energy needed to cause a chemical reaction to occur is the?
The amount of energy necessary to cause a chemical reaction to occur is called activation energy.
What Protein are responsible for all chemical reaction that occur in cells - these proteins lock smaller molecules together and separate larger molecules?
Enzymes
What effect does an enzyme have on Ea?
Enzymes lower the activation energy (Ea) required for a chemical reaction to occur. By binding to reactant molecules and stabilizing the transition state, enzymes facilitate the formation of products from substrates. This acceleration of the reaction reduces the amount of energy needed to initiate the reaction, making it more favorable and allowing it to occur at a faster rate.
What are 3 conditions that necessary for a reaction to occur?
There are many factors that affect the occurance of a chemical reaction. If the reaction you are using has any buffer or catalyst than you should be selective in that keeping in mind your reactants and product. The temperature required for any particular reaction to occur should also be kept in mind.
What happens when hydrogen and oxygen molecules form water?
A chemical reaction between oxygen and hydrogen occur.
What does an energy diagram give?
It shows the energy requirements needed in order for a reaction to occur.
What are three reasons why enzymes are important?
Enzymes are biological catalysts. They allow the reaction to occur, basically putting together molecules to allow the reaction to happen. They increase the rate of reaction without changing the outcome of the reaction. Increasing the rate of reaction so these reactions can occur fast enough to support life.
