form spindle fibres (e)

Question 3

lysosomes

Answer 3

break down-digestive enzymes (e)

Question 4

protein and lipid modifications (e)

Question 7

mitochondria

Answer 7

site of aerobic respiration

Question 8

cell membrane

Answer 8

control movement of substances in and out of the cell

Question 9

nucelolus

Answer 9

where ribosomes are made

Question 10

nucelus

Answer 10

contain genetic material- dna

Question 11

nuclear pore

Answer 11

gap in nucleus

Question 12

Rough ER

Answer 12

protein processing- fold tertiary structure

Question 13

mesosome

Answer 13

site of respiration (p)

Question 14

capsule

Answer 14

protection (p)

Question 15

plasmid

Answer 15

contain genetic material (p)

Question 16

peptidoglycan cell wall

Answer 16

protect from dehydration (p)

Question 17

circular DNA

Answer 17

genetic code (P)

Question 18

pili

Answer 18

attachment (p)

Question 19

protein transport

Answer 19

amino acids joined together to form polypeptide chain on a ribosome attached to rER.
polypeptide pass through cisterna into rER lumen- folding polypeptide to tertiary structure
rEr package protein nit vesicles
vesicle fuse with Golgi apparatus
protein modified as move through golgi body
enzyme packaged into secretory vesicle
fuse with cell surface membrane exit by exocytosis

Question 20

extracellular enzyme

Answer 20

biological catalyst outside the cell
