Biology
catabolic reaction (with example)
complex molecules are broken down into simpler molecules, respiration/digestion.
anabolic reaction (with example)
Simple molecules converted into more complex molecules, photosynthesis/protein synthesis
explain specificity in relation to enzymes
an enzyme can only react with one substrate e.g amylase only rescts with starch
metabolism
the sum of all chemical reactions in a cell
denaturation
enzyme looses shape and no longer works because of conditions outside optimum PH+temp
active site
part of enzyme that combines with the substrate
immobilised enzymes
enzymes that are attched, or fixed to eachother or an inert material
advantages of immobilised enzymes
can be reused
can be recovered
produce a pure product
example of catabolic and anabolic emzyme
catabolic= amylase, lipase, pepsin
anabolic= DNA ligase
what is an enzyme?
a biological catalyst made from protein
what is a catalyst?
an enzyme that speeds up a reaction without being used up itself
