Q

Cell Membrane

A
  • regulates movement of substances in and out of cells.
  • selectively permeable
  • irregular shaped to allow for more surface area
  • made of liquids and proteins.

17
Q

Metabolism Function

A

Chemical reactions processing energy which keep cells and organisms alive

18
Q

ATP (Adenosine Triphosphate)

A

Source of energy for use and storage at a cellular level (certain things must enter and exit the cell)

19
Q

ACTIVE MECHANICS

A

Transports: move particles from low to high concentration

Endocytosis & Exocytosis: processes that move molecules in and out of cell w/o passing though membrane

20
Q

PASSIVE MECHANICS
(no energy required)

A

Diffusion: molecules move from low to high concentration

Osmosis: Movement of water across semipermeable membrane

Filtration: Molecules move through membranes by random movement

21
Q

CELL CYCLE

A

(A call forms & grows for a period of time before maturing enough to divide)
- increase in size
- copying DNA
- splits DNA in nucleus in 1/2 after preparation stage (interphase)
- cell divides & cycle repeats

22
Q

Chemistry

A

Study of composition of matter

23
Q

Matter

A

Everything that has weight and takes up space

24
Q

Element

A

What all matter is made of

25
Q

INORGANIC SUBSTANCES

A

Water
Oxygen
Carbon Dioxide
Salts

26
Q

Water

A

solvent that moves chemicals (blood) in body

27
Q

Oxygen

A

Enters through respiration
carried by red blood cells
cellular organelles use it to release energy and drive metabolic process

28
Q

Carbon Dioxide

A

Produces as waste product when metabolic process releases energy (respiration

29
Q

Salts

A

Charged ions needed by tissues,
metabolic process uses; transportation of substances, muscle contraction, impulse conduction of nerve cells

30
Q

ORGANIC SUBSTANCES

A

Carbohydrates
Sugars
Lipids
Phospholipid
Proteins
Glycoproteins
Amino Acids

31
Q

Carbohydrates

A

provides energy for cells

32
Q

Sugars

A

Smallest carbohydrate molecules

33
Q

Lipids

A

Insoluable in water but soluble in some organic substances

34
Q

Phospholipid

A

Phosphate group & fatty acid portion of cell structure

35
Q

Proteins

A

Structure/energy sources as receptors of cells

36
Q

Glycoproteins

A

Formed protein and carbohydrates functioning as cell receptors

37
Q

Amino Acids

A

Building blocks of proteins (20 types)

38
Q

ORGANIC SUBSTANCES: NUCLEIC ACIDS
(Forms genes and takes part in protein synthesis)

A

Nucleotide
nucleic acids– DNA & RNA

39
Q

Nucleotides

A

Contains a 5-carbon sugar, a phosphate group, and one of several nitrogenous bases

40
Q

2 Types of Nucleic Acids

A

RNA
DNA

41
Q

RNA

A

Ribonucleic Acid

42
Q

DNA

A

Deoxyribonucleic Acid
