What does a catalyst do?
Reduces the activation energy for chemical reactions to occur.
What reduces Activation energy?
Catalyst
What is a chemical reaction?
A process that leads to a chemical transformation of one set of chemical substances to another.
What is the process called that leads to the chemical transformation of one set of chemical substances to another?
Chemical reaction
What is activation energy?
The energy required to have a reaction.
What is the energy to have a reaction called?
Activation energy
What is substrate?
Reactant
What is a reactant?
Substrate
What is the active site?
Where enzymes and sub-straits bond together
What is the location where enzymes and substraits bond
Active site
What are the properties of enzymes?
Reaction specific
Not consumed in reaction
Made of protein
Affected by cellular conditions
One key fits one?
Lock
What happens to reaction rate when the enzyme concentration goes up?
Also goes up
What happens to the reaction rate when the substrate concentration goes up?
Also goes up
Why is the reaction rate low on low temperatures?
not enough successful collisions
Why is the reaction rate low on high temperatures?
Enzymes denature
