Q

The active site and substrate don’t fit perfectly together;
instead, they both alter their shape to connect

A

induced-fit model

17
Q

a substrate binds to an enzyme (via the
active site) to form an enzyme-substrate complex

A

Normal Enzyme Reaction

18
Q

enzyme + substrate =

A

enzyme-substrate complex

19
Q

involves a molecule, other than the substrate, binding to the enzymes active site

A

Competitive innibition

20
Q

Competitive innibition involves a molecule, other than the substrate, binding to the enzymes___

21
Q

the molecule (inhibitors) structurally and chemically similar to the substrate hence able to bing to the active site

A

Competitive Inhibitor

22
Q

blocks the active site and thus prevents substrate binding

A

competitive inhibitor

23
Q

As the Inhibitors is in competition with the substrate. Its effects can be reduced by?

A

increasing the substrate concentration

24
Q

enzyme + inhibitor

A

enzyme- inhibitor complex

25
involves a molecule binding to a site other than the active site (an allosteric site)
