1)  carbon compounds.  

2) 4

3)  covalent 

4) They were incorporated into organic molecules by plants. They were processed into sugars through photosynthesis. They are ultimately derived from carbon dioxide.

5)  The majority of their bonds are nonpolar covalent carbon-to-hydrogen linkages.

6) structural isomers.

7) arrangement of carbon, hydrogen, and oxygen atoms.

27)  d

28)  b

29) d

30) a

31)  b

32)  d

33) a

34)  It is negatively charged. It has acid properties.

35) contain only hydrogen and carbon atoms.

36) the study of carbon compounds.

37)  hydrocarbons.

38)  the replacement of the hydroxyl of a carboxyl group with hydrogen

39) amino

40)  glucose

41) the removal of water (dehydration reactions) 

42)  Dehydration reactions assemble polymers, and hydrolysis breaks down polymers.

 

43)  carbohydrate.

 44) polysaccharide. 

45)  humans have enzymes that can hydrolyze the alpha (α) glycosidic linkages of starch but not the beta (β) glycosidic linkages of cellulose. 

46)  They are insoluble in water. They are an important constituent of cell membranes. They contain twice as much energy as an equivalent weight of polysaccharide. 

47) lipid made with three fatty acids and glycerol. 

48) have a higher ratio of hydrogen to carbon than do unsaturated fatty acids.

49) a saturated fatty acid

50) unsaturated fatty acid.

51)  polymer of amino acids.

52)  side chains (R groups).

53)  peptide bond.

54) removal of a water molecule 

55) are synthesized from monomers by dehydration reactions. 

56) triacylglycerides polysaccharides proteins 

57)  c

58)  a

59)  e

60) peptide bonds

61)  hydrogen bonds

62)  hydrogen bonds

63) primary secondary tertiary quaternary

64) DNA --> RNA --> proteins 

65)  a nitrogenous base, a phosphate group, and a pentose sugar 

66)  contains one less oxygen atom.

67complementary pairing of the nitrogenous bases. 

68)  the reaction of a fat, forming glycerol and fatty acids with the utilization of water

69) in which carbon, hydrogen, and oxygen are present in a ratio of 1:2:1.

70)  catabolism

71)  Living organisms can convert energy among several different forms. Living organisms can use energy to do work. Organisms expend energy in order to decrease their entropy 

72)  ATP serves as a main energy shuttle inside cells. ATP drives endergonic reactions in the cell by the enzymatic transfer of the phosphate group to specific reactants. The regeneration of ATP from ADP and phosphate is an endergonic reaction.

73)  Add a catalyst.

74)  lowering the energy of activation of a reaction.

75)  curve 3 

76) curve 4

77)  coenzyme 

78) 

Enzymes may require a nonprotein cofactor or ion for catalysis to take place.

Enzyme function is reduced if the three-dimensional structure or conformation of an enzyme is altered.

Enzyme function is influenced by physical and chemical environmental factors such as pH and temperature.

Enzymes increase the rate of chemical reaction by lowering activation energy barriers.

79) cellular respiration 

80)  their enzymes have high optimal temperatures.
