Key Terms Flashcards
What is activation energy?
Energy required to bring about a reaction. Activation energy is lowered by enzymes.
What is the active site?
Group of amino acids, making up the region of an enzyme, which the substrate fits in order to catalyse a reaction
What is an allosteric site?
Region of an enzyme, to which a non-competitive inhibit of mines
What is a competitive inhibitor?
Molecule that binds to the active site of an enzyme, preventing the substrate from binding.
What is denaturation?
Permanent changes due to the unravelling of the 3-D structure of a protein as a result of factors, such as changes in temperature or pH
Enzyme
Protein or rna acts as a catalyst alters speed of biochemical reactions
What is an enzyme substrate complex?
When is substrate binds to the active site of an enzyme most likely resulting in a reaction formation of products 
What is the induced fit hypothesis?
When the active site of an enzyme changes shape in response to the substrate
What is kinetic energy?
Energy, that’s an object possesses due to its motion
What is the lock and key hypothesis?
When the active site of an enzyme is perfectly complementary to the substrate
What is a non-competitive inhibitor
Molecule that binds to an anaesthetic site, therefore changing enzyme active site, preventing substrate from binding
What is a product?
Molecules formed from a reaction
What is a substrate?
Reactants in a reaction, catalyse by an enzyme has a shape complimentary to the active site
What is a successful collision?
When a substrate enters the active site of an enzyme at the correct speed and orientation
What is the tertiary structure?
Folding of a whole poly peptide chain in a precise way, as determined by the amino acids are what its composed
