level questions: Level 1 of Enzymes

QuestionAnswer
Enzymes functions-SPECIFIC TERTIARY STRUCTURE -SPECIFIC ACTIVE SHAPE -ONLY COMPLEMENTARY TO THE ACTIVE SITE -LOWER ACTIVATION ENERGY
Lock and Key theoryactive site is complimentary
Induced fit theoryThe acitve site is not complimentary so it changes the active site
endings of enymes and their meaningase- carbohydrate - glycosidic bond ease-protein- peptide
Factors affecting rate of reaction-enzyme concentration (run out substrates for es complexes) -substrate concentration increases so more es complexes then substrate conc is no longer the limiting factor ( max es complexes not enough enzymes) -temperature (kinetic energy increases so more collisions creating es complexes quicker until it reaches optimum temp and the max everything until it suceeds this then causes hydrogen/ionic bonds in enzyme to break Causes enzyme’s ts to change,so active s changes no longer compimentary) PH (ph changes cause hydrogen bonds to break in the specific tertiarty structure)
What is a competitive inhibitor ?inhhibitor competes with the substrate for the active site and binds preventing the substrate and active site binding so the rate of r is slower
Keywords for when an enzyme denatures.Bonds break Tertiary structure Active site shape Not complementary No ES complexes
Enzyme denaturesBonds break -hydrogen and ionic bonds in the enzyme break Tertiary structure - changes Active site shape -this causes the active site shape to change Not complementary -not complementary to active site So no ES complexes form
