BLOCK 2

Question 1

gated transport

Answer 1

whole folded protein is moved via aqueous pores (post translational)

Question 2

transmembrane transport

Answer 2

folded or unfolded protein moves via non-aqueous transport complexes (post or co translational)

Question 3

vesicular transport

Answer 3

protein is transported in small vesicles that fuse with target component (after transmembrane transport)

Question 4

post translational transport

Answer 4

after whole protein has been made; typically involves chaperones to keep protein unfolded in cytoplasm

Question 5

co-translational transport

Answer 5

simultaneously with protein synthesis

Question 6

targeting signals: no label

Answer 6

cystolic protein, default

Question 7

targeting signals

Answer 7

short sequences of amino acids

Question 8

nuclear envelope

Answer 8

double membrane surrounding the nucleus; outer membrane is continuous with the ER

nuclear pore complex

Question 9

nuclear pore complex

Answer 9

controls entry and exit into the nucleus

Question 10

luclear lamina

Answer 10

meshwork of intermediate filaments (lamins) under the nuclear envelope

Question 11

mRNAs leave nucleus as….

Answer 11

mRNPS

Question 12

mRNPS

Answer 12

ribonucleoprotein particles

Question 13

ribosomal subunits

Answer 13

made in nucleolus and go to cytoplasm
