enzymes Flashcards
what is an enzyme
biological catalyst
describe in detail the active site theory of enzyme action
-the substrate combines with the active site of the enzyme
-the active site is induced to caused to change shape slightly
-the substrate and enzyme form an enzyme substrate complex. the bonds in the substrate are altered so that the substrate changes into products
describe what happens to an enzyme if it is overheated
becomes denatured
give one example of a catabolic enzyme and one example of a anabolic enzyme
catabolic - amylase
anabolic - polymerase
what is meant specify in relation to enzymes
only acts on one substrate
what type of metabolic reaction is the induced fit model
catabolic
why is the induced fit model a catabolic reaction
substrate is broken down
identify the cell organelle where enzymes,es are produced
ribosome
what is meany the enzyme denaturation
loss of shape
give one condition that will denature an enzyme,e
unsuitable pH
what is an immobilised enzyme
an exam that is fixed
give one advantage of using immobilised enzymes
can be reused
which type of biomolecule are enzymes
protein
name two factors that affect the enzyme action
temperature, pH
name the part of an enzyme responsible for its specificity
active site
