27
Q

the predominate part of muscles, skin, nerves and hair; organelles; Antibodies; Enzymes

28
Q

Provide energy for the tissues although energy production is not the main function.

29
Q

Composed of building blocks called amino acids (aa)

30
Q

Amino groups are made up of

A

Amino group (NH2); Carboxyl group (COOH); R groups

31
Q

R groups

A

represents a number of different structures and differentiate one aa from another.

32
Q

The sequence of aa are determind by ____ and the type of protein they make.

33
Q

essential aa

A

aa that the body is not capable of making. you can only obtain them from your diet

34
Q

When aa are joined together, a water molecule is removed

A

dehydration synthesis

35
Q

when a covalent bond is form between the carboxyl group of one aa and an amino group from another

A

peptide bond

36
Q

chains of aa are called ?

A

polypeptides

37
Q

Denaturation are (reversible or permanent change?)

A

reversible

38
Q

Physical or Chemical factors that disrupt bonds cause..

A

changes in the shape of the protein.

39
Q

Denaturation; Once the physical or chemical factor is removed, the protein may assume…

A

original state

40
Q

A permanent change in protein shape

A

Coagulation

41
Q

Coagulation; The proteins in the egg are said to have coagulated because no matter how much cooling takes place, they will never assume

A

their original state

42
Q

Two ways of increasing the rate of reactions

A

Increase temperature and using catalysts

43
Q

what are enzymes?

44
Q

Enzymes are proteins specialized for..

A

specific tasks

45
Q

All chemical reactions in living organisms require _________ to work

46
Q

Synthesis

47
Q

digestion

48
Q

Enzymes are protein catalysts and reduce the reactions..

A

activation energy

49
Q

The molecule on which an enzyme works on.

50
Q

The area that joins the enzyme with the substrate molecule

A

Active site

51
Q

The enzyme’s active site is like a ____ and ____ mechanism

A

Lock and Key

52
Q

When the enzyme temporarily joins with the substrate this forms an

A

Enzyme-substrate complex

53
Q

Factors affectinv enzyme reactions

A

1.Temperature 2.pH 3.Substrate Molecule Concentration 4.Conpetitive inhibitors 5.Non-competitive inhibitors

54
Q

when the temperature is too high, bonds are _____ and when too low, bonds are not _______

A

too high= weak
too low= flexible

55
Q

Most humans function optimally between pH..

56
Q

The greater the # of substrate molecules -> the greater the # of collisions -> the greater the rate of..

57
Q

Molecules have shapes similar to that of the substrate. Taking up the car spot

A

Competitive inhibitors

58
Q

Changes the shape and active site of the enzyme. taking half of the car spot

A
