Q

Cells synthesize various types of molecules, including proteins, nucleic acids, and lipids. The different cells of the body do not all produce the same molecules. Therefore, the structural and functional characteristics of cells are determined by the types of molecules they produce.

phosphate

51
Q

A

FLOW OF GENETIC INFORMATION

52
Q

flow of genetic information Occurs in three stages:

A
  • DNA replication
  • Transcription
  • Translation
53
Q

information in DNA directs protein synthesis

A

GENE EXPRESSION

54
Q

process by which DNA is “read”

A

TRANSCRIPTION

55
Q

process by mRNA is converted into amino acids (polypeptides)

56
Q

movement of molecules form areas of high to low concentration

57
Q

or more solutes

58

A

FACILITATED DIFFUSION

63
Q

moves substances from low to high

concentration

A

ACTIVE TRANSPORT

64
Q

involves the diffusion of water down the concentration gradient through a selectively permeable membrane.

65
Q

TYPES OF OSMOTIC SOLUTIONS

A
  • HYPOTONIC SOLUTION
  • HYPERTONIC SOLUTION
  • ISOTONIC SOLUTION
66
Q

lower concentration of solutes outside cell

A

HYPOTONIC SOLUTION

67
Q

The solute concentration outside the cell is less
than the concentration inside the cell. Therefore, the water concentration outside is greater than that inside, and water flows into the cell.

A

HYPOTONIC SOLUTION

68
Q

higher concentration of solutes outside cell

A

HYPERTONIC SOLUTION

69
Q

The solute concentration outside the cell is
greater than the concentration inside the cell. Therefore, the water concentration is greater inside the cell than outside, and water flows out of the cell.

A

HYPERTONIC SOLUTION

70
Q

equal concentration of solutes

A

ISOTONIC SOLUTION

71
Q

The solute concentration outside the cell is the
same as that inside the cell. Therefore, water concentration is also the same on both sides of the cell, and the net movement of water is zero

A

ISOTONIC SOLUTION

72
Q

process that brings materials into cell using vesicles

A

ENDOCYTOSIS

73
Q

TYPES OF ENDOCYTOSIS

A

Phagocytosis

Pinocytosis

74
Q

The cell “eats” large particles such as bacteria, viruses, and dead cells.

A

Phagocytosis

75
Q

The cell periodically “drinks” by

forming small vesicles around droplets of extracellular fluid.

A

Pinocytosis

76
Q

process that carries materials out of cell using vesicles

A

EXOCYTOSIS

77
Q

formation of 2 daughter cells from a single parent cell

A

CELL DIVISON

78
Q

each cell (except sperm and egg) contains

A

46 CHROMOSOMES

79
Q

sperm and egg contain

A

33 CHROMOSOMES

80
Q

cell division that occurs in all cells except sex cells

81
Q

STAGES IN MITOSIS

A
  • INTERPHASE
  • PROPHASE
  • ANAPHASE
  • TELOPHASE
82
Q

time between cell divisions

A

Interphase

83
Q

chromatin condenses into chromosomes

84
Q

The centromeres divide, forming two chromosomes instead of a pair of attached chromatids

85
Q

the two new nuclei assume their normal

structure, and cell division is completed, producing two new daughter cells.
