49
Q

sweep “stuff”

50
Q

cellular respiration equation

A

C6H1206 + O2 -> CO2 + H2O + energy

51
Q

contraste chromatin and chromosomes

A

DNA within nucleus as long, thin threads- chromatin

when preparing to divide, DNA becomes highly coiled and condensed -chromosomes

52
Q

how many chromosomes do human cells have

A

46 chromosomes - 23 pairs

53
Q

mircotubules- cytoskeleton

A

thickest; straight hollow rods

54
Q

microfilament- cytoskeleton

A

thinnest; solid rods of protein

55
Q

intermediate filaments- cytoskeleton

A

helps maintain cell shape; anchor certain organelles in place

56
Q

how do our body cells get energy

A

from food
Digestive system breaks complex polymers down into monomers-simple molecules absorbed- carried to our cells- some used to make ATP

57
Q

the breakdown of glucose without O2

A

fermentation

58
Q

difference between cellular respiration and fermentation

A

cellular- requires O2

fermentation- doesn’t

59
Q

name of C6H12O6

60
Q

4 phases of cellular respiration

A

glycolysis
transition reaction
citric acid cycle
electron transport chain

61
Q

where does glycolysis occur in the cell

62
Q

where does transition reaction occur in the cell

A

mitochondria

63
Q

where does citric acid cycle occur in the cell

A

mitochondria

64
Q

where does electron transport chain occur in the cell

A

mitochondria

65
Q

total yield of ATP for cellular respiration and fermentation

A

c.r.- 36 ATP

fer-2 ATP glucose

66
Q

which is more energy efficient- cellular respiration or fermentation

A

cellular respiration

67
Q

how many ATP are formed throughout the process of cellular respiration

68
Q

during what parts of cellular respiration were they made

A

2 during glycolysis, 2 during citric acid cycle, 32 during ETC

69
Q

what is the difference between aerobic and anaerobic

A

aerobic- oxygen is required

anaerobic- oxygen is not required

70
Q

what happens to CO2 that is made during cellular respiration

A

diffused out of cells into blood and taken to lungs to be exhaled

71
Q

since not all of glucose energy is used to make atp what happens to the rest of the energy

A

the rest is lost as heat

72
Q

explain the condition in which fermentation occurs

A

process stops at end of glycolysis

73
Q

where does lactic acid fermentation occur

74
Q

when does lactic acid fermentation occur

A

we make lactic acid in our muscles cells when theres not enough O2 to make more ATP

75
Q

lactic acid builds up in muscles

76
Q

when O2 is finally available

A

lactic acid is transported to liver and converted to continue on in the aerobic cellular respiration process

golgi complex

88
Q

cellular energy is in what form

89
Q

break down carbohydrates and sugars in order to use the energy stored in them (ATP) the energy currency of the cell—–make ATP

90
Q

purpose of fermentation

A

breakdown glucose without oxygen

91
Q

where does the carbohydrates and oxygen of cellular respiration come from

A

carbs from glucose

oxygen from body

92
Q

contains genetic info that is passed on from generation to generation

93
Q

openings in the nuclear envelope

A

nuclear pores

94
Q

allow communication between nucleus and cytoplasm

A

nuclear pores

95
Q

region in nucleus where ribosomal RNA is produced

96
Q

where amino acids are assembled into proteins

97
Q

found in two forms:freely in cytoplasm or attached to rough er

98
Q

secretes substances out of cell through membrane

A

101
Q

digest ingested materials and destroy nonfunctional organelles

102
Q

converts carbs to atp through cellular respiration

A

mitochondria

103
Q

complex network of fibers within cytoplasm

A

cytoskeleton

104
Q

when does fermentation occur

A

when there is no oxygen and process stops at end of glycolysis
