Medicinal Biochemistry- Enzymes properties & Enzyme kinetics

Which of the following statement is wrong

• Enzymes are Biocatalyst which enhances rate of reaction without getting consumed

• Enzymes almost all are protein in nature

• Enzymes generally are thermostable

• Enzymes are specific in their action

Enzyme molecule contains a special pocket or cleft called as

• Special area

• Special site

• Active membrane

• Active site

Holoenzyme means

• Apoenzyme + Protein

• Apoenzyme + Apoprotein

• Protein compound + activator

• Inorganic metalion + organic molecule

Which of the following is true regarding Co-factor

• Co-factor are inactivators of the enzyme

• Co-factors includes only co-enzymes

• Co-factors are activators of the enzyme

• Co-factors are protein in nature

Which of the following regarding enzyme properties are correct

• Enzymes are non-specific in nature

• Many enzymes follow compartmentalization

• Enymes had many

Study of enezyme kinetics is useful for measuring

• Concentration of enzyme in a mixtre

• its purity

• effect of activators

• effect of inhibitors

Michael's constant (Km) is defined as the substrate concentration at which the reaction velocity is...................maximal

• Half

• One

• One & half

• double

In zero order reaction, rate of reaction is independent of

• product concentration

• substrate concentration

• Both A & B

• None of the above

Low Km value indicates

• Strong affinity between enzymes

• Strong affinity between products

• Strong affinity between enzyme and substrate

• Strong affinity between enzyme & product

Line weaver burk double reciprocal plot equation is similar to

• Y= ab+X

• Y= aX-b

• Y= aX+b

• Y=ab-X
