enzymes Flashcards
what is an enzyme?
a biological catalyst that’s speeds up reaction in our cells
are enzymes unchanged by the reactions?
no
can enzymes be used more than once?
yes
what are the 4 parts of an enzyme reaction?
substrate
enzyme
active site
products
what is the function of an enzyme?
the function of an enzyme is that it speeds up chemical reactions without being used up its self
what is an actives sites function?
the area on an enzyme where the sub rate binds to
what is the substrates function?
the molecule the at binds to the active site
what is the function of the products ?
the result of an enzyme reaction that is realised from the active site
what is enzyme specificity?
the shape of the active is comprlemtary to only one substrate
what is a synthesis reaction?
a synthesis reaction is a type of enzyme reaction that’s results in a build up of smaller molecules into larger molecules
what is a degredation reaction?
a degredation reaction is a type of enzyme reaction that results in the break down a large molecule into smaller molecules
what are the two factors that can effect enzyme activity?
pH and temp
when id enzyme activity at its best?
when the enzyme is in its optimum temp of pH
what happens when an enzyme becomes denatured?
the shape of the enzyme changes so that it is no longer complemeanaru to its specific substrate. this slows down or stops the activity of the enzyme
