Q

haemoglobin is comprised of what

A

heme molecule and globin molecule

20
Q

heme molecules are formed from what

A

succinyl- CoA and glycine (4 of these molecules bind together with iron)

21
Q

cells can be two types which are

A

prokaryotic or eukaryotic

22
Q

eukaryote cells are

A

oragnisms that are made up of eukaryotic cells

23
Q

prokaryote is a

A

prokaryotic cell

24
Q

Nucleus contain

A

containing genetic material that controls the activities of the cell

25
Q

cytoplasm is

A

a gel like substance where most of the chemical reactions happen, it contains enzymes that control these chemical reactionsc

26
Q

cell membrane is

A

holds the cell together and controls what goes in and out

27
Q

mitochrondria is

A

where most of the reactions for aerobic repiration take place. respiration transfers energy that the cell need to work

28
Q

ribosomes are

A

where the proteins are made in the cell

29
Q

bacterial cells are called

A

prokaryotes

30
Q

do bacterial cells have a nucleus

A

no they have a single circular strand of dna that floats freely in the cytoplasm

31
Q

what are plasmids

A

they are small rings of dna contained in a prokaryote cell

32
Q

what is differentiation

A

the process by which a cell changes to become specialised for its job

33
Q

as cells change they develop different …. …. and turn into different types of cells which allows them to carry out specific functions

A

subcellular structures

34
Q

4 specialised cells

A

sperm cells,
nerve cells
muscle cells

35
Q

sperm cells are specialised for

A

reproduction

36
Q

nerve cells are specialised for

A

rapid signalling

37
Q

muscle cells are specialised for

A

contraction

38
Q

the nucleus contains your genetic material in the form of

A

chromasomes

39
Q

chromosomes are coiled up lengths of

A

dna molecules

40
Q

each chromosome carries a large number of

A

genes

41
Q

different genes control the development of different

A

characteristics i.e. hair colours

42
Q

how many pairs of chromosomes are in a human cell

A

32

43
Q

body cells in multicellular organisms —- to produce new cells as part of a series of stages called the – —

A

divide, cell cycle

44
Q

the stage of the cell cycle when the cell divides is called

A

mitosis

45
Q

multicellular organisms use mitosis to

A

grow or replace cells that have been damaged
