enzymes
what are enzymes
special proteins rhat regulate chemical reactjons im the body
what is a catalyst?
a substance rhat helps to imcreae the rate of a chemical reaction
define activesite
the region on an enzyme which the substrate binds to
define substrate
a molecule on which an enzyme acts (reactant)
what are the three charactwristics of an enzyme
each enzyme has an active site
enzymes are very specific
enzymes are recycled
what are enzyme inhibitors?
control the functioning enzymes.
what are the two types of enzyme inhibitors?
competitive and non-competitive
what is competitive inhibition?
a molecule other than the intended substrate binds to the active sute and blocks the substrate
what is non-competitive inhibition
when a momecule binds to a site (not actibe site) which causes the shape of the enzyme to change
what is activation energy?
a certain amount of energy required to begin a reaction
what can tou use to increase rhe rate of a chemical reavtikn
catalysts
what is the ateucture of an enzyme
long chains of amino acids
globular shape with holes and pockets
what happens during a enzyme catakyzed reavtion
the enzyme and substrate join to form an enzyme substrate complex
