1.4 Enzymes Biology N5

enzymes help speed up cellular reactions (biological catalyst)

after the reaction they remain unchanged

protein

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

a substare is the substance that a enzyme acts on

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.

degradation and synthesis

during a degradation reaction large complex molecules are broken down into small simpler molecules

the breakdown of starch imto maltose using the enzyme amylase the breakdown of hydriogen peroxide into water and oxygen using the enzyme catalase

in a synthesis reaction small simple molecules are built bup into largert more complex molecules

glucose-1-phosphate is made into starch using the enzyme potato phosphorylayse

enzyme specificity mean sthat that a enzyme works with only one type of substrate

they are the conditions where a enzyme is most active
