1.4 Enzymes Biology N5 Flashcards
what is the function of enzymes
enzymes help speed up cellular reactions (biological catalyst)
what happens to the enzymes after the reaction
after the reaction they remain unchanged
what are enzymes made out of
protein
why may enzymes stop fuctioning
enzymes may stop functioning because the temprature is to high so they become denatured or the tempraturew may be to low so they are functioning at a low rate
what is a substrate
a substare is the substance that a enzyme acts on
what happens during the reaction
during a reaction the substrate attaches to the enzyme at the active site on the enzyme molecule which creates a enzyme substrate complex whic alllows the reaction to occur the action crreates several ort just one pproduct.
what two reactions do enzyme catalyse
degradation and synthesis
what happens during na degradation reaction
during a degradation reaction large complex molecules are broken down into small simpler molecules
examplles of degradation molecules
the breakdown of starch imto maltose using the enzyme amylase
the breakdown of hydriogen peroxide into water and oxygen using the enzyme catalase
what ocuurrs during a synthesis reaction
in a synthesis reaction small simple molecules are built bup into largert more complex molecules
describe a example of a synthesis reaction
glucose-1-phosphate is made into starch using the enzyme potato phosphorylayse
what is ment by enzyme specifity
enzyme specificity mean sthat that a enzyme works with only one type of substrate
what are optimum conditions
they are the conditions where a enzyme is most active
name another factor that affects the enzyme other than temprature
PH
