Pack 4 - Protein And Enzymes

Question 1

Explain how the active site of an enzyme causes high rate of reaction

Answer 1

Lowers activation energy
Indeed fit causes active site of enzyme to change shape
Enzyme substrate complex causes bonds to break or form

Question 2

High temp effect enzyme

Answer 2

Enzyme denatures from a high temp
High energy causes enzyme to vibrate which breaks hydrogen and iconic bonds
So tertiary structure unravels
Peptide bonds are vey strong so never break

Question 3

Ph affect enzyme

Answer 3

Acid and alkaline interfere which hydrogen and ionic bonds so enzyme denatures
