b2 - enzyme at ph scale

what does the enzyme speed up?

enzyme speed up chemical reactions

the lock and keytheory - what is specific,what fits perfectly into the active site?

the lock and key theory enzymes are specific, the substrate must fit perfectly into the active site

(b) enzyme binds to the substrate because they are complementary (shapes),(so) substrate is broken down (into products),(so) products are released o

as ….. inc the activity of the ……… ………

as the temp increases,the activity of the enzyme increases

explain ph values

enzymes are protein molecules so have a 3d strucutre,at ph values above or below the optimm the shape of active site is changed in some moelcules so substrate can no longer fit the active site so the enzyme is denatured

what happens if you make the ph more acidic or alkaline the activity…. .. . …,active site …….

if we make ph more acidic or alkaline the activity drops to 0,active site denatures
