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

Answer 16

induced-fit model

Question 17

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

Answer 17

Normal Enzyme Reaction

Question 20

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

Answer 20

active site

Question 21

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

Answer 21

Competitive Inhibitor

Question 22

blocks the active site and thus prevents substrate binding
