Answer 6

p_fluidgy

Question 7

volume flow rate formula

Answer 7

quaternary structure

Answer 8

• the interaction of multiple protein subunits to form a complex

Question 9

what does the signal recognition particle identify?

Answer 9

• partially translated mRNA-ribosome complexes with a targeting sequence in the cytosol and targets them to the rough ER, at which point translation continues and post translational modification are added

Question 10

when can hydride shifts occur

Answer 10

• not from an enolate but only from a carbocation intermediate

Question 11

equation relating momentum to kinetic energy

Answer 11

p= sqrt (2Km)

Question 12

calculation for magnification

Answer 12

-i/o

Question 13

when given an energy of ionization problem

Answer 13

• draw out the electron configuration

Question 14

the compound that will precipitate first given Ksb

Answer 14

• has the lowest solubility

Question 15

the acetylcholine receptor in the neuromuscular junction

Answer 15

• a ligand-gated sodium channel

Question 16

p53

Answer 16

• tumor suppressor gene that prevents movement through the cell cycle in the event of DNA damage, thus giving time for the DNA to be repaired.

Question 17

dorsal root ganglion

Answer 17

• the location of the neuron cell body where protein production occurs
• most likely origin for channel proteins that would subsequently become embedded in the neuron cell membrane

Question 18

ELISA is the preferred method for

Answer 18

• secreted proteins found in the media, blood, or extracellular space.

Question 19

the interior of a cell membrane is hydrophilic or hydrophobic?

Answer 19

• hydrophobic

Question 20

all mercury salts with the exception of mercuric nitrate are

Answer 20

• insoluble

Question 21

recombination only occurs where?

Answer 21

• meiosis

Question 22

spleen

Answer 22

• major organs of immune system

- rich with lymphocytes and serves a major resource in the body’s natural defenses against pathogens

Question 23

• where are RBC synthesized?

Answer 23

• red bone marrow

Question 24

concentric rings that surround the central circular region of bone contain

Answer 24

• blood or lymph vessels

Question 25

where are osteocytes found

Answer 25

• small spaces along channels branching away from the central channel

Question 26

where are chondrocytes found

Answer 26

• cartilage

Question 27

big difference between protists and bacteria

Answer 27

- both are unicellular, have ds DNA, and use flagellar motility

Question 28

proteins are synthesized how

Answer 28

• by the condensation of amino acids through dehydration synthesis

Question 29

which instrumental conditioning schedule leads to the quickest increase in rate of desired responses?

Answer 29
