Q

In the dynamic state of body constituents - concept ofmetabolism has one of the greatest discoveries in which it state that some of the biomolecules have turn over

A

False it say all biomolecules have turn over

26
Q

Example of turn over

A

Glucose

27
Q

Pigments are

A

Carotenoids and anthoycanin

28
Q

We isolated thousand of compund , small and big from living organisms for

A

Determining their structure and if possible synthesising them

29
Q

Alkaliod

A

Morphine and codenie

30
Q

Terpenoids

A

Monoterpens and diterpens

31
Q

Essential oil

A

Leman , grass oil

32
Q

Toxins are

A

Abrin , recin

33
Q

Lectins

A

Concanavalin A

34
Q

Drugs

A

Vinblastine, curcumin

35
Q

Polymeric substance

A

Rubber , gums , cellulose

36
Q

Animals have another variant called —–

A

Glycogen

37
Q

Which end is reducing end and why

A

Right rlend because on that side there is free oxygen and it can bind freely with anyone.so

38
Q

Example of complex polysacchride

A

Glucosamine ,N - acetyl galactosamine

39
Q

Cellulose not response to blue colour why

A

Because it do not have helical structure

40
Q

Thermus aquatic bacteria is thermostablebactetia

A

False thermophilic bacteria

41
Q

Taq. Polymerase enzyme is thermophilic enzyme

A

False thermostable enzyme

42
Q

Thousand of types of enzyme each catalysing a unique chemical or metabolic reaction

A

True

43
Q

When each os step is cataylsed by same enzymecomplex or different enzyme is called a

A

Metabolic pathway

44
Q

Transient phenomenon means

A

Means active site वर substrate येऊन बिंड करतो आणि ES form होत

45
Q

Substrate bind ton active site and a new structure of the substrate form called

A

Transition state structure

46
Q

The structure of product get formed on the subtrate

A

Wrong structure of substrate form into product

47
Q

ES is shorted lived

A

Correct

48
Q

The substrate in the active site bind within the structure called c

A

Clift or pocket

49
Q

In the exothermic reaction or spontaneous rection the relation between substrate and product

A
  1. In the graph of exo reaction,
    The substrate is more than product
    S>P,
50
Q

In the endothermic reaction the relation between substrate and product is

A

The substrate is less and product is more
P>S

51
Q

Activation energy means

A

1The average energy differences between substrate and transition state
2. The energy required to convert substrate into transition state to form product

52
Q

Enzyme always functional at narrow temperature

A

No
Enzyme are generally functional at narrow temperature (40°c temp)

53
Q

Activity of enzyme declined ————— the optimum value

A

Both above and below

54
Q

At high temperature perseved enzyme in permanent inactive state

A

False
At low temperatures preserved enzyme is temporarily inactive in its state

55
Q

A= at high temperature enzyme destroyed enzymatic activity
R=the proteins are featured by a heat

A

Correct explanation

56
Q

A=The reaction ultimately the maximum velocity which is not exceeded by any further rise in concentration of the substrates
R= the enzyme molecules are fewer than substrate molecule

A

Correct explanation

57
Q

Example of compitive inhibitor

A

Inhibition of succinic dehydrogenase by malonate

58
Q

Compitive inhibitor are oftenly controlled by

A

Bacterial pathogens

59
Q

Inthe compitive inhibitor substrate size and inhibitor size is same or not

A

Same
And in non compitive inhibitor substrate size and inhibitor size is not same

60
Q

Noncompitive inhibitor binds to

A

Alosteric site

61
Q

Relation between Km and affinity between substrate and product

A

1Kmmore the affinity between substrate and product less
2. Km less the affinity between substrate and product is more
