2.4 Chemical Reactions And Enzymes Flashcards
What is a chemical reaction?
A process that changes chemical compounds.
What are reactants
They enter a chemical reaction
What is the definition of products
They are produced by chemical reactions.
Uses more activation energy
Endothermic
Uses less activation energy
Exothermic
What is released / absorbed when chemical bonds are broken
Energy
What is the energy of activation
Energy needed to start a chemical reaction
Which reaction is more likely to start spontaneously
Eco thermos because it uses less activation energy
How does the addition of a catalyst affect the energy of activation in a chemical reaction
When a catalyst is added it decreases the amount of activation energy needed and speeds up the reactions.
What type of catalyst affects biochemical reactions
An enzyme
What make proteins the ideal type of compounds for enzymes
They break down and build things up
Remember
Substrates attach to enzyme
Substrates are made into products
Products are released
How is a substrate and enzyme work like a lock and a key
One key fits into one lock
One substrate fits into one enzyme
What is being unlocked in the lock and key analogy
The bonds in reactants/ products
What is the. Enifit of having controls over the chemical reactions that take place in their body
They can adapt better and faster
