Chemical Reaction And Enzymes Flashcards
What are enzymes?
Biological Catalyst
What do catalyst do?
Speed up chemical reactions
How do enzymes speed up chemical reactions?
By lowering the activation energy.
Can any enzyme catalyze any chemical reaction?
No, specific enzymes fit with specific substrates.
What bonds with enzymes at the active sites?
Specific substrates.
What is released by the enzyme after the chemical reaction has taken place?
The product
Are enzymes used up?
No, they are reused over and over.
What can effect the effectiveness of enzymes?
Temperature and pH
__________ are on the left side of a chemical reaction
Reactants
__________ are on the right side of a chemical reaction
Products
What is equilibrium?
When products and reactants are made at the same rate.
Describe exothermic reactions.
Reactions that release more energy than they absorb.
Describe endothermic reactions.
Reactions that release less energy than they absorb.
What is activation energy?
The amount of energy needed to be absorbed before the chemical reaction can take place.
