Question 0

Cont

Answer 0

Shape and size
Analogy " lock and key " 
Enzymes bind to hold
Random collisions
Feasible by providing alternative 
Lower activation energy

Question 1

Enzymes

Answer 1

Biological catalyst
Specific with substrate 
Enzymes are protein. 
Adopt confirmations
Active site

Question 2

Binding of substrate

Answer 2

Sequence of aa linked by peptide bond to form polymeric enzyme.
Some r groups are polar and not dissociated
Functional groups can be dissociated and Charged

Question 3

Cont

Answer 3

Weak and reversible

Enzymes bind substrate hormones bind their receptors. Antibodies bind antigens

Question 4

Prividin alternative route

Answer 4

Different route has lower activation energy

Action of enzyme is chymotrypsin present in small intestine catalyses hydrolysis of peptide bonds. Helps digest protein
